Render Branch: evil "local" option for material light groups. When the material
is linked in, this will use a local group instead of the linked group, so that
some objects in a linked group can be lit by separate lights.

Implementation is just a few lines in material.c, most of the changes do some
clean up for lamp related code.

support for adding remove action groups, as well as setting an action group from an fcurve (was readonly).

COLLADA branch: importer fix - loc/scale animation was being read incorrectly. Discovered this while fixing bug #21768.

Render Branch: Fix ward isotropic slope option not showing in UI.

Render Branch: Fix unused material node affecting final color.

FCurve Py/RNA API for adding and removing points fcu.keyframe_points.add()/remove()
mostly rewritten but some parts taken from [#21313] Added API Function to manage F-Curve. By Anthony Hinsinger (atoy40)

Armature NLA baking function, very simple but not in any menu's yet.
- bakes armatures only
- bakes loc/scale/rot
- supports different rotation types
- cleans up unneeded points after.

attempt to fix for dna padding error on some systems

fix for own errors in calling ending topology table

appending a data that linked to another blend file would fail to save that link because it didnt tag it as directly linked.

COLLADA branch: fix bug #21768 - animation channel target was incomplete for translation and scaling animation.

Render Branch: Sun lamps now can cast soft shadows again. They look
different however than trunk, because they used to depend on the lamp
location while the light depends only on the rotation. So that has
changed now and only the rotation should have an influence. This also
means the soft size does not define a size in blender units, but rather
a fraction of the hemisphere.

fix for topology mirror table not being freed

Render Branch:
* Option Use Local Coords for raytracing was enabled when the option
in the UI was disabled.
* Avoid creating tangents on high res mesh when doing tangents space
high to low baking.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.

Solidify
- offset option so the surface can be made solid from the middle
- vertex group, so solid distance can be multiplied by a vertex group (invert option also)
