Blender Git Loki

These updates enable the build of the gameengine
(configure --enable-gameengine). However, you still need to manually configure,
compile and install ode.

* Following the original NaN makefile, I removed the TerraplayNetwork files
from the build. (Moved the two files to EXTRA_DIST).

* Pass a const char * to Py_BuildValue instead of a STR_String in
BL_ActionActuator.cpp

* Added some include directories in Makefile.am's
