	Usage Note:
	-----------
	Do not use both ajaxSubmit and ajaxForm on the same form.  These
	functions are intended to be exclusive.  Use ajaxSubmit if you want
	to bind your own submit handler to the form.  For example,

	$(document).ready(function() {
		$('#myForm').bind('submit', function() {
			$(this).ajaxSubmit({
				target: '#output'
			});
			return false; // <-- important!
		});
	});

	Use ajaxForm when you want the plugin to manage all the event binding
	for you.  For example,

	$(document).ready(function() {
		$('#myForm').ajaxForm({
			target: '#output'
		});
	});

	When using ajaxForm, the ajaxSubmit function will be invoked for you
	at the appropriate time.

/**
 * ajaxForm() provides a mechanism for fully automating form submission.

 * 1: This method will include coordinates for <input type="image" /> elements (if the element
 *	is used to submit the form).
 * 2. This method will include the submit element's name/value data (for the element that was
 *	used to submit the form).
 * 3. This method binds the submit() method to the form for you.
 *
 * The options argument for ajaxForm works exactly as it does for ajaxSubmit.  ajaxForm merely
 * passes the options argument along after properly binding events for submit elements and
 * the form itself.

// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.7, Safari 3-4,
//                   Chrome 4-5, Opera 9.6-10.1.
// Unit Tests      - http://benalman.com/code/projects/jquery-bbq/unit/
// 
// About: Release History
// 
// 1.2.1 - (2/17/2010) Actually fixed the stale window.location Safari bug from
//         <jQuery hashchange event> in BBQ, which was the main reason for the
//         previous release!
// 1.2   - (2/16/2010) Integrated <jQuery hashchange event> v1.2, which fixes a
//         Safari bug, the event can now be bound before DOM ready, and IE6/7
//         page should no longer scroll when the event is first bound. Also
//         added the <jQuery.param.fragment.noEscape> method, and reworked the
//         <hashchange event (BBQ)> internal "add" method to be compatible with
//         changes made to the jQuery 1.4.2 special events API.
// 1.1.1 - (1/22/2010) Integrated <jQuery hashchange event> v1.1, which fixes an
//         obscure IE8 EmulateIE7 meta tag compatibility mode bug.
// 1.1   - (1/9/2010) Broke out the jQuery BBQ event.special <hashchange event>
//         functionality into a separate plugin for users who want just the
//         basic event & back button support, without all the extra awesomeness
//         that BBQ provides. This plugin will be included as part of jQuery BBQ,
//         but also be available separately. See <jQuery hashchange event>
//         plugin for more information. Also added the <jQuery.bbq.removeState>
//         method and added additional <jQuery.deparam> examples.
// 1.0.3 - (12/2/2009) Fixed an issue in IE 6 where location.search and
//         location.hash would report incorrectly if the hash contained the ?
//         character. Also <jQuery.param.querystring> and <jQuery.param.fragment>
//         will no longer parse params out of a URL that doesn't contain ? or #,
//         respectively.
// 1.0.2 - (10/10/2009) Fixed an issue in IE 6/7 where the hidden IFRAME caused
//         a "This page contains both secure and nonsecure items." warning when
//         used on an https:// page.
// 1.0.1 - (10/7/2009) Fixed an issue in IE 8. Since both "IE7" and "IE8
//         Compatibility View" modes erroneously report that the browser
//         supports the native window.onhashchange event, a slightly more
//         robust test needed to be added.

// in which this plugin can be used.

// 
// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.7, Safari 3-4, Chrome, Opera 9.6-10.1.
// Unit Tests      - http://benalman.com/code/projects/jquery-hashchange/unit/
// 
// About: Known issues
// 
// While this jQuery hashchange event implementation is quite stable and robust,
// there are a few unfortunate browser bugs surrounding expected hashchange
// event-based behaviors, independent of any JavaScript window.onhashchange
// abstraction. See the following examples for more information:
// 
// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
// 
// About: Release History
// 
// 1.2   - (2/11/2010) Fixed a bug where coming back to a page using this plugin
//         from a page on another domain would cause an error in Safari 4. Also,
//         IE6/7 Iframe is now inserted after the body (this actually works),
//         which prevents the page from scrolling when the event is first bound.
//         Event can also now be bound before DOM ready, but it won't be usable
//         before then in IE6/7.
// 1.1   - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
//         where browser version is incorrectly reported as 8.0, despite
//         inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
// 1.0   - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
//         window.onhashchange functionality into a separate plugin for users
//         who want just the basic event & back button support, without all the
//         extra awesomeness that BBQ provides. This plugin will be included as
//         part of jQuery BBQ, but also be available separately.

(function($,window,undefined){
  '$:nomunge'; // Used by YUI compressor.
  
  // Method / object references.
  var fake_onhashchange,
    jq_event_special = $.event.special,

    return url.replace( /^[^#]*#?(.*)$/, '$1' );

  // polling loop executes. Defaults to 100.

  // Event: hashchange event
  // 
  // Fired when location.hash changes. In browsers that support it, the native
  // window.onhashchange event is used (IE8, FF3.6), otherwise a polling loop is
  // initialized, running every <jQuery.hashchangeDelay> milliseconds to see if
  // the hash has changed. In IE 6 and 7, a hidden Iframe is created to allow
  // the back button and hash-based history to work.
  // 
  // Usage:
  // 
  // > $(window).bind( 'hashchange', function(e) {
  // >   var hash = location.hash;
  // >   ...
  // > });
  // 
  // Additional Notes:
  // 
  // * The polling loop and Iframe are not created until at least one callback
  //   is actually bound to 'hashchange'.
  // * If you need the bound callback(s) to execute immediately, in cases where
  //   the page 'state' exists on page load (via bookmark or page refresh, for
  //   example) use $(window).trigger( 'hashchange' );
  // * The event can be bound before DOM ready, but since it won't be usable
  //   before then in IE6/7 (due to the necessary Iframe), recommended usage is
  //   to bind it inside a $(document).ready() callback.
