[Bf-python] update to Apply_def.py

[Campbell Barton]

Hi, just updated Apply_def.py to use Mesh over NMesh,
Changed it from a mesh script to an object script and it works with non 
mesh objects that have a display list.

Is it too late to update, Theeth what do you think?

__bpydoc__ = """\
This script creates "raw" copies of deformed meshes.

Usage:

Select the mesh(es) and run this script.  A fixed copy of each selected mesh
will be created, with the word "_def" appended to its name. If an object 
with
the same name already exists, it appends a number at the end as Blender 
itself does.

Meshes in Blender can be deformed by armatures, lattices, curve objects 
and subdivision, but this will only change its appearance on screen and 
rendered
images -- the actual mesh data is still simpler, with vertices in an 
original
"rest" position and less vertices than the subdivided version.

Use this script if you want a "real" version of the deformed mesh, so 
you can
directly manipulate or export its data.
