/*
 * The function captureFlashEvents should be called with appropriate values from out a flash app whenever
 * button clicks a/o player events shall be tracked down to e given tracking system. Current implementation supports
 * omniture sitecatalyst versions H.x. Support of other tracking tools can be adopted by changing the generic code
 * w/o changing anything within ActionScript of the Flash app's.
 * This Function should be called with the ActionScript function getUrl(...):
 * ...
 *	getUrl("javascript:captureFlashEvents(....)");
 * ...
 * The Script needs to be available in the current surrounding HTML page itself and must apply to the Flash
 * sandbox model.
 *
 * Parameters:
 * FlashName		-		Name of Flash File as String
 * FrameName		-		Name of a Frame if applicable, else empty String (!)
 * Sekunde		-		Time since start for Media as String, format should be something like '00:00'
 * EventBezeichnung 	-		Name of the Event as String
 * UseCookie		-		whether data should be stored in a cookie for the next page to
 *							submit data to the underlying tracking system as Boolean
