Remove extraneous code

Merge branch 'master' into temp_bmesh_multires

Sculpt dyntopo: Exposed UV smooth bruth in experimental features prefs.

* Also got undo working for it

Sculpt dyntopo: Wrote a little UV smoother sculpt brush.
It uses a simple LSCM-like solver; hold ctrl to do simple
laplacian relaxation.

There are some interesting artistic possibilities to using
DynTopo with UV maps, the point of this tool is to help
explore them.

Note that I'm not planning to merge this into master with
the rest of this branch. When the time comes I plan to
move it into a new branch for sculpt research stuff.

Array Brush: Scale and stroke strength working

Array Brush: Count and deform mode brush properties

Array Brush: Working code for path and radial arrays

Sculpt Array: Debug path drawing

Sculpt Array: Initial code for path and path points

Array Brush: Implement symmetry datalayers

Sculpt dyntopo: Add support for multiple materials to dyntopo
pbvh drawing.

* Dyntopo now stores a list of PBVHTriBufs in leaf nodes, one per material
used by the node.
* Actual drawing buffers live in a new mat_draw_buffers PBVHNode member.

Array Brush: Implement array instances datalayer

Array Brush: BMesh duplication working
