@short factory to create frameloader-objects
@descr These class can be used to create new loader for specified contents.
We use cached values of the registry to lay down, wich frameloader match
a given URL or filtername. To do this, we use the XMultiServiceFactory-interface.
@ATTENTION In a specialmode of these implementation we support a simple filterdetection.
But there is no special interface. You must call some existing methods in another context!
see createInstanceWithArguments() fo rfurther informations!
