Set default brush spacing to 15%

* Filled out LAYERTYPEINFO and LAYERNAMETYPES for the new custom data types I added.

fixed crash in quadview

COLLADA branch: change texture coordinate parameter names from X and Y to spec-compliant S and T.

Brush strength should not be reduced if brush spacing is not enabled.

fixed object id bug

* disabled openmp for now
* created a function calc_area_normal_and_flatten_center to get rid of the loop over head of calculating them seperately
* changed stroke spacing to be a percentage of brush size instead of absolute pixels
* UI for stroke spacing now goes from 1-500 percent
* the power of overlapping strokes is attenuated by one minus of the amount of circle overlap
* tweaked clay brush strength upwards to account for attenuation
* clay now obey's the accumulate checkbox

Fix indexMat typo and linking problem on Linux with make.

crash fix and clay brush strength fix

Completely removed thread safe path in calc_area_normal that was causing crash when used with multires. Only half-way making the necessary changes to disable it is what created the unstable code.

Made clay brush strength dependent on the projected radius of the brush so that it has the same apparent effect no matter what scale the user zooms.

merged with head

Fixed crash with sculpt draw tool and multires.

Its really fixed this time, I promise :)

Fixed crash bug with sculpt+multires introduced by optimizations

Optimizations to sculpt: simplified calc_flatten_center, simplified point/plane projection, removed use of memset/calloc from performance critical areas, removed creation of undo points from places they weren't needed. Based on profiling the bottleneck is not in sculpt code anymore

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r28753:29022

COLLADA branch:
* partially fix #22388 by appending mesh object name to skin controller id (according to the patch provided by Tod Liverseed) (exporter). Importer still incorrectly handles the case when multiple meshes are linked to a single armature.
* add GPL blocks mentioning contributors. Hopefully didn't miss anyone.

Render Branch: hair collision time stepping test. Not sure this is much
better than before but it helps in some cases. It seems to me that
without this it is taking 1.5 steps each time instead of 1.

The original paper defines vi+1/2 = (xi+1 - xi)/dt, but in our case we
already have vi+1 = (xi+1 - xi)/dt ... so there's a conflict here.

Render Branch: fix missing hardness property for Cook-Torrance in UI.

Render Branch: make hair particles also support drawing their number next
to them, previously this only worked for regular particles.

Render Branch: for hair collisions, always treat quads as split into
triangles for intersections, solves some issues.
