better support for static inner classes
It is now possible to use `A.X` to refer to inner classes from outside 
the enclosing class and access the static members of the class.
Still not possible to call `new A.X` and not sure if this is needed.
See #213 and https://github.com/wurstscript/WurstStdlib2/issues/275
