Added material and image handling/hooks and the constant dictionaries.
Changed Image.h and Material.h to only have public declarations, so
NMesh could include them.
Jacques Guignot (guignot) sent updated files for his Curve module.
* Module Armature (and its submodule Bone) added:
Jordi Rovira i Bonet (bandoler) contributed both modules, which
are NEW additions to Blender Python, not available in Blender 2.27.
* Added function to NMesh.c:
Jordi again. He added the function NMesh_getVertexInfluence().
Found that syntax errors in scripts were giving SIGSEGV, my mistake.
* Added new helper type: rgbTuple.
This is used to represent and deal with rgb color triplets in modules
like Material and Lamp. Updated Lamp module to use it.
Partially implemented. Most of it comes from opy_nmesh.c, plus needed
changes to integrate in into exppython.
* Added helper submodule vector, needed by NMesh.
* Minor changes in other files.
