/**
 * Used by the Diablo Flash to display a Games Arcade flash minigame over the top of Moshi.  This function is called by the 
 * Diablo Flash via an External Interface call.  The Flash will supply all the details required to display the game; these
 * are passed through to the arcade-wrapper.html.  When the minigame is closed another ExternalInterface call will be made
 * to the Flash which will cause Moshi to resume.
 *
 * This function makes use of FancyBox to display a custom iFrame (FunParkLauncher.jsp) which hosts the minigame's SWF file.
 * FancyBox uses jQuery which is only included inline in MyMonster.jsp - not ideal.
 *
 * @see FancyBox API: http://fancybox.net/api
 *
 * @param gameDetails (Object)	An arguments object which contains the following properties:
 *		- swf: 				The filename for the minigame's SWF, ie: "games/jungle-plunge.swf"
 *		- swfVersion: 		Minimum Flash Player Version required to play the SWF
 *		- width: 			Width of the minigame in pixels
 *		- height:			Height of the minigame in pixels.
 * 
 * @param controlsImageURL (String) The filepath for the minigame's controls image, 
 * 									ie: "controls/jungle-plunge-controls.jpg"
