GSShape.shapeType returns boolean

[RafalBuchner]

GSShape.shapeType returns boolean

Accordingly to docs, it should return integer value :

'''
.. attribute:: shapeType
the type of the shapes. can be GSShapeTypePath or GSShapeTypeComponent

	:type: int

'''

@schriftgestalt Do you want me to update the wrapper, so it actually returns integer?, or should I change documentation to something else (maybe you changed returned type on some purpose ? )
