 *  Free beer and free speech. Enjoy!
 *
 *  This plugin converts anchor tags into Quicktime objects.
 *  Examples and documentation at: http://malsup.com/jquery/media/
 *
 *  Options are passed to the 'quicktime' function using an object literal.
 *  The following option keys are supported:
 *
 *  Options:
 *  -------
 *  width:       width of quicktime player[1] (default: 200)
 *  height:      height of quicktime player[1] (default: 200)
 *  version:     version of quicktime player required (default: '6,0,2,0')
 *  cls:         classname(s) to be applied to new element (default: anchor's classname)
 *  src:         source location of quicktime .mov file (default: value of href attr)
 *  caption:     text to be used as caption; use false for no caption (default: value of anchor text)
 *  attrs:       hash of attributes for the object/embed tags; eg: { autoplay: false } (default: empty object)
 *  elementType: type of element to replace anchor (span, div, etc) (default: 'div')
 *
 *  [1] height and width values can be embedded in the classname like this: <a class="quicktime w:450 h:450></a>
 *
 *  Example: convert all anchors with class of 'quicktime' to quicktime objects:
 *  $('a.quicktime').quicktime();
 *
 *  Example: convert myMovie anchor to quicktime object with no caption and explicit values 
 *           for autoplay, tabindex and title:
 *  $('#myMovie').quicktime( {
 *      attrs:   { autoplay: false, tabindex: 10, title: 'My Title' },
 *      caption: false
 *  } );
