wrapper functionality by hand.
* Removed the swig files (*.i and *_wrap.c)
* Created initial datablock functionality. Most of it has been copied from
the old implementation.
* Created some general functions in gen_utils.[ch]
* Blender.Get(), Blender.Set() and Blender.Redraw functions should work in a
script now.
* Started implementation on an Event function call (BPY_do_pyscript)
