Add blender launcher application when building with MSVC

Main idea of this change is to make a small executable which
will set OMP_WAIT_POLICY environment variable and then will
launch blender itself.

This is a teporary solution for the time being we'll have a
more clear solution to high CPU usage with OpenMP when building
with MSVC.

T41354, cursor never gets reactivated in uv sculpting.

Fix crash on dyntopo when show diffuse option + collapse is used

Some nodes could end up without any faces and in that case getting a
face material would fail.

Fix T41333: Selected mask points don't stand out visually.

Looks like mask points coloring was recently changed, and IMAGE space colors were left uninitialized...
Factorized a bit the code about vertex_handle & co too, was quite duplicated.

Cleanup: Remove special code for Visual Studio 2008.

Goodbye VC2008, it has been a pleasure (more or less) :D SCons / CMake cleaenup will follow.

Experimental gooseberry request:

Expose radial control properties. That way, the operator can be tweaked
in the input preferences to tweak other properties as well.

change scons default to be visual studio 2013

Comments

BMesh: use existing lookup tables when remapping

GHash/EdgeHash: avoid NULL check on iterator init

Fix T41047: Text objects flipping

UI: move button to set dupli-offset into group menu

Fix T41323: Sequencer: video window taking all the place when switching to split view.

Issue is that, when we switch from full preview view to combined view, preview area has
its `sizey` set to use all available height, which leaves nothing for poor main area.

For now, make checks when switching mode to combined one, so that both areas have
resonable `sizey` values. Not perfect, but works.

Cleanup: mostly move together main area init/draw/handler callback, and some generic cleanup (tabs, comments...).

Fix T41343, hard to remove group from objects.

Added a small menu with a few helper oerators next to each group panel:

* Remove group from all objects
* Select objects in group

More could be added possibly in the future.

Thanks to Campbell for the advice here.
