Sculpt dyntopo: another attempt to fix undo memory corruption bug

adaptive_cloth: fix: Mesh: split_edge_triangulate() crash when edges are realloced

Took the new edge index by reference instead of copy leading to wrong memory access when the edges are reallocated by the arena.

Knife: Added undo functionality

Pressing ctrl-z will now undo the most recent cut segment made.
When drag cutting undo reverts each segment of the cut individually.
Currently this breaks visible distance and angle measurements after using undo but a fix will be committed soon.

adaptive_cloth: Mesh: make split_edge_triangulate() work with new deletion methods

adaptive_cloth: Mesh: delink face edges

adaptive_cloth: Mesh: const get checked elements

Fix implicit int error

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

adaptive_cloth: Mesh: better deletion of the elements

This new way of deleting elements ensures that no links can be missed out on. The deletion of the elements has to happen in a certain order leading to lesser number of errors.

This is API breaking, so all functions refering to deletion of the elements have to be updated. This includes, Mesh::split_edge_triangulate() and Mesh::collapse_edge_triangulate().

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.

Physics: Added visualisation for trimesh collision shape type

Thumbnail Job - Version 1

The current code has been tested and three areas it breaks.
1) refreshing a bunch of times
2) strip slide
3) multiple strips.
Multiple strip support is being worked on now. Other points are bugs.

Consistent var naming, function usage.
