Inter-mesh snap optimization and fixes.
For larger meshes, tests are made against the bounding box first to speed things up (suggested by Brecht).
Also, verts are accessed through mesh_get_mapped_verts_nors() it can snapped to deformed vertices (only the deformed originals, not new verts for now).
New option "rotate around selection" failed in editmode, when nothing was
selected.
Function calculateCenterMedian() missed that case.
Also added some zero initializing in code.
A check is now performed to see if any markers were deleted before adding an undo-push, so you don't need to CTRL+Z twice to un-delete keys in the Action Editor if you didn't have any markers selected.
* Tablet pressure sensitivity for number field dragging
Many of the number fields in Blender are very sensitive. With this addition,
softer tablet pressure causes the number field dragging to be more precise,
as if you're holding shift, but variable depending on how hard or soft
you're pressing. You can push hard for large adjustments or just lightly
stroke it for fine tuning.
P.S. There was a bug in the tracker regarding tablet support in sculpt mode that
never really got resolved. I don't know if it still exists, but number fields
are a pretty major part of Blender, so just in case this commit causes problems
for you, you can disable it (temporarily, this won't be left in) by changing
rt: to any value other than 0. If anyone has problems, please report them, and
we can get it sorted out properly.
"Copy To Linked" option for VertexGroups copied the vertexgroups of the active mesh to all meshes in the scene, not just the ones that used the same mesh datablock.
Added an option to choose between Catmull-Clark and simple subdivision when adding a level. This setting applies only to how the level is created; any changes to lower levels are still propagated to the top level using Catmull-Clark.

Definition of default "bpy" module was decrementing reference count, which
caused assertion errors on Windows. This fixes the problem on Linux; Win
developers please test!
Action Channels can now be collapsed/expanded to show/hide Constraint Channels, lessening clutter. In future, this could (will probably be) expanded to
show the show/hide individual transform channels.
User Notes:
* Expansion is off by default
* NKEY popup now features option to turn expansion on/off
* Changed behaviour of protection a bit - now if an action channel has protection
on, constraint channels under it are also automagically protected
Developer Notes:
* I've gone through doing a lot of whitespace/linebreak tweaking to get the code looking more consistent with itself
* To save typing (and to make it easier to make future revisions), a set of macros
is now used to check for some commonly-checked settings (i.e. selection, visibility,
and protection).
packing 2400 rectanges is about 38x faster.
Use the C implimentation in uvcalc_lightmap and uvcalc_smart_project
Blender.c - filename returning None raises errors with existing scripts, just return "" so string functions on the filename dont raise an error.
