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) Michel
