[Pyobjc-dev] NSBitmapImageRep support

[Bill B. <bb...@co...>]

NSBitmapImageRep can now be used from PyObjC.  ObjCPointer probably 
should go away as the methods used for NSData and NSBIR seem to work 
really well.

The support for NSData and NSBIR is currently incomplete, but they are 
usable.

See the unit test for example usage.  The NSBIR unit test needs to be 
fixed as it currently writes files to /tmp/ and shouldn't.
