create actor xml and documentation based on its class

./kepler.sh -createActorXML arg where arg is either full class name or path to java file.

The ports or parameter variables should be exactly the same with what will appear in Kepler GUI. For instance, recursive = new Parameter(this, "recursive"); And the comments of these variables should also be correct since they will appear in actor xml and documentation.

The semantics of the actor should be edited manually at the actor xml file.

The command will also automatically create LSID for the actor and update resources/kar/Actors/MANIFEST.MF file at corresponding module. Change it if needed.
