option for cyclic time adjustment for nla strips, needed for adjusting the speed of flapping wings

Fix cancelling while computing irradiance cache not responding fast enough.

include library in the tooltip

view selected uses display transform bone

simplify version checking by having addons use same version tuple as bpy.app.version

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r27521:27541

no need to include the setting names in enum items

option to lock alpha while projection painting.

transform marker sync for extend and grab is back.

the string 'Environment' is too long for a pass name, was causing crashes in FSA. use Env instead.

no need to set flat shading for faces manually

adding faces was setting the wrong flag, smooth rather then selected.

Render Branch: don't do shade once trick for strands now, this does not
work well at the moment. Full shading also leads to blurry color textures
at the moment, will have to think of a way around this.

Render Branch: indirect light shading / bump. The bump method settings
has been removed and replaced with a shading method setting. There are
three options:

* No Shading: no bump mapping and assuming lambert shader.
* Full Shading: execute BSDF for each ray and includes bump mapping. When
combined with irradiance cache, will generally require many more samples
for bumped surfaces and execute textures 2x.
* Shade Once: execute BSDF once using averaged ligth direction for each
RGB channel. Bump mapping is also done after irradiance caching this way.
Requires fewer samples in irradiance cache and only needs to do textures
once. This is basically the trick from "An Approximate Global Illumination
System for Computer Generated Films" used by Dreamworks.

Decided to use averaged light direction instead of spherical harmonics,
uses less memory and these can be used with BSDF's. This trick is not really
accurate but seems believable enough for e.g. Minnaert and Oren-Nayar shaders,
though for example with Toon it fails to give similar results.

This commit also fixes AO falloff strength not being taken into account.

Render Branch: move displacement code into own file, and some code cleaning
for transforming mesh normals.

Render Branch: tweak to ambient occlusion multiply mode, now it is also
applied to env/indirect intead of only direct light.

Render Branch: make displacement work with flat shading, previously would not
have properly set normal giving strange result, though in general it's best to
use smooth shading for displacement to avoid discontinuities at the edges.

Wkey in uv editor brings up weld/align menu rather then welding.
