//
// Visit http://abeautifulsite.net/notebook/62 for more information
//
// Usage: $('#control_id').multiSelect( options, callback )
//
// Options:  selectAll          - whether or not to display the Select All option; true/false, default = true
//           selectAllText      - text to display for selecting/unselecting all options simultaneously
//           noneSelected       - text to display when there are no selected items in the list
//           oneOrMoreSelected  - text to display when there are one or more selected items in the list
//                                (note: you can use % as a placeholder for the number of items selected).
//                                Use * to show a comma separated list of all selected; default = '% selected'
//
// Dependencies:  jQuery 1.2.6 or higher (http://jquery.com/)
//
// Change Log:
//
//		1.0.1	- Updated to work with jQuery 1.2.6+ (no longer requires the dimensions plugin)
//				- Changed $(this).offset() to $(this).position(), per James' and Jono's suggestions
//
//		1.0.2	- Fixed issue where dropdown doesn't scroll up/down with keyboard shortcuts
//				- Changed '$' in setTimeout to use 'jQuery' to support jQuery.noConflict
//				- Renamed from jqueryMultiSelect.* to jquery.multiSelect.* per the standard recommended at
//				  http://docs.jquery.com/Plugins/Authoring (does not affect API methods)
//
//		1.0.3	- Now uses the bgiframe plugin (if it exists) to fix the IE6 layering bug.
//              - Forces IE6 to use a min-height of 200px (this needs to be added to the options)
