[Robotics] Python control of armature in the GE

[Markus Mehrwald]

Hi,

I just managed it to compile the branch with the ikplugin. For some 
reasons I was not able to compile because of a few errors. I think its 
just some little changes in the CMake files. First of all the BIK_api.h 
was not found. I did it quick and dirty by copying the full path in the 
files where it is needed. The second thing was that obviously the libs 
bf_ikplugin and bf_ITASC are not in the list of libs to link against.
Maybe you did not update the CMakeList or was it a problem of my computer?

Regards,
Markus
