2.5: * Image painting back. 2d paint, 3d paint and projection, undo, pressure, repeating paint operations, etc should all work. Drawing cursor needs a bit of work, only gets shown when enabling texture paint mode now. * Move sculpt, image paint, and vertex/weight paint into a single sculpt_paint module. Doesn't make much difference now, but nice to have it together for better integration and consistency in the future.

Changed vertexpaint and weightpaint to use the standard Brush struct, so they too work with the brush panel. Note: these modes are only using color/alpha/size from Brush, so there's more integration work todo yet.

(NOTE: DO NOT TEST) Start of planned DerivedMesh refactoring. The mface interfaces in DerivedMesh have been renamed to reflect their new status as tesselated face interfaces (rather then the primary ones, which are now stored in mpolys). short review: mpolys store "primary" face data, while mfaces store the tesselated form of the mesh (generally as triangles). mpolys are defined by mloops, and each mpoly defines a range of loops it "owns" in the main mloop array. I've also added basic read-only face iterators, which are implemented for CDDM, ccgsubsurf, and the bmeditmesh derivedmesh. Since faces are now variable-length things, trying to implement the same interface as mfaces would not have worked well (especially since faces are stored as an mpoly + a range of mloops). I figure first we can evaluate these simple read-only face iterators, then decide if a) we like using iterators in DerivedMesh, b) how much of it should use them, and c) if we want write-capable iterators. I plan to write official docs on this design after I get it more stable; I'm committing now because there's a rather lot of changes, and I might do a merge soon.
