/**
 *  Flash plugin for converting anchors into flash objects.

 *  Free beer and free speech. Enjoy!
 *
 *  This plugin converts anchor tags into flash objects.
 *  Demos can be found at: http://malsup.com/jquery/media/
 *
 *  NOTE:  This plugin uses (and requires) swfobject.js for proper flash detection.
 *         You must include swfobjects.js on any page that uses this plugin.
 *         @see http://blog.deconcept.com/swfobject/
 *
 *
 *  Sample HTML:
 *      before:  <a href="myMovie.swf" class="flash">Watch my movie!</a>
 *
 *      after:   <div class="flash"><object ... <embed ...   <br />Watch my movie!</div>
 *
 *  Usage:
 *      $('a.flash').flash();
 *
 *  Or using options:
 *      $('a.flash').flash({
 *          caption:  false // supress caption text
 *      });
 *
 *
 *  Notes:
 *  -----
 *  The base tag doesn't *have* to be an anchor but it makes a lot of sense to do it that way
 *  so please consider it. If you use something other than an anchor you'll need to provide
 *  an options argument with a src attribute set to the path of the media file.
 *
 *  By default, classnames assigned to the anchor will be assigned to the div.  This makes it
 *  convenient for styling:
 *
 *  <style type="text/css">
 *      a.flash { ... }
 *      div.flash { ... }
 *  </style>
 *
 *  Options are passed to the 'flash' function using a single Object.  The options
 *  Object is a hash of key/value pairs.  The following option keys are supported:
 *
 *  Options:
 *  -------
 *  width:       width of flash player* (default: 450)
 *  height:      height of flash player* (default: 370)
 *  version:     version of flash player* required (default: 7)
 *  background:  background color of flash player* (default: #fff)
 *  cls:         classname(s) to be applied to new element (default: anchor classname)
 *  src:         source location of flash .swf file (default: value of href attr)
 *  caption:     text to be used as caption; use false for no caption (default: value of anchor text)
 *  params:      object which holds parameters for the object/embed tags (default: empty object)
 *  flashvars:   object which holds parameters for the flashvars attribute (default: empty object)
 *  elementType: type of element to replace anchor (span, div, etc) (default: 'div')
 *
 *  * height, width, version and background values can be embedded in the classname using the following syntax:
 *  fallback added p.scheit fallback bezeichnet das fallbackdiv
 *    <a class="flash w:450 h:450 ver:7 bg:fff fallback: #id></a>
