Implemented enough functionality to actually execute Python from within

Blender.
* Moved api2_2x/interface.c to ./BPY_interface.c
  This will be the general api layer from which all variants of the Blender
  api. Currently only the 2.2x variant is initialised.
* Used swig (www.swig.org) to create Python wrappers for a couple of dummy
  functions.
* Started implementation of the Blender and Blender.Object modules.
