Included required resources in jars

Static resources are stored along source files in our current layout.
Therefore we set resourceDirectory to be sourceDirectory but make sure
that includeFilter includes nothing by default. Subprojects like library
or compiler set their own include filters.

The include filters have been ported from the Ant build definition.

Generate properties for: library, reflect, compiler & actors.
