Blender Git Loki

Fixed file loading for multires (broken during merge), also corrected
linker flags so I can link with the gold linker.

Everything in the branch should once again compile.

Synch more files from trunk

Added/corrected more files from the merge.

Resynch gameengine

Resynch a couple more directories with trunk

Replaced this branch's intern directory with trunk's.

Added files missed during the merge.

Nasty merge from trunk's r18216.

Handle the (extremely unlikely) case that the max multires levels is exceeded

A couple of very minor cleanups

Updated sculptmode's anchored brush to work with the new multires.

Subsurf UVs with the multires modifier.

Based on user feedback, changed the default curve from the sinusoidal shape to a sharper point. Makes the default brush less blobby.

Moved the Multires/Sculpt undo data into the multires modifier. Also fixed up the way the data is free'd to fix a bug that made it appear sculpting had been lost after doing an undo.

Fixed a bug caused by counting DM faces rather than faces in the original mesh.

Also removed an unused function.

Better support for triangles with the new tangent calculations.

WIP: Fixed tangents for vertices of valence 3. Still need to look at handling triangles better.

WIP: Switched the displacer over to using the new tangents. Mostly works, except for valence-3 vertices.

WIP: Moved calculating the TS matrix into it's own function, since it's getting a bit complicated now.
