[Bf-python] BMesh python api proposal.

[Dima Glibitsky]

A related question: would it be possible to have a "shortcut" access
to the derived mesh used for rendering? Currently the only way is to
call obj.to_mesh(scene, apply_modifiers=True, settings='PREVIEW'),
which creates a new datablock.

It would be useful to have something like this:
obj.get_visible_derived_mesh(scene) -- returns the Derived Mesh object
(without creating new ID block)

...By the way, will derived meshes be considered another kind of ID
blocks, or will they get status similar to Vector/Matrix objects?
