initial bmesh python api.

Browse Source 
corrently allows to create and loop over verts/edges/faces, access selection and selection modes.

this is still WIP, access to face, edge verts is still missing, no access to UV's, no access to editing operations yet.

When the api is ready it will be documented by sphinx like mathutils, blf, aud.
