Cycles OpenCL error to string removed in favour of the same function in clew.
Fix to get iTaSC working again in the BGE
BGE: Fix bug with Steering Actuator Python API.

It was not possible to set the navmesh attribute from Python due to a double bug.
Intensity and color are now adjusted upon import to get correct values
UI: show ttips even if disabled, when holding alt key.

Patch by @sambler (Shane Ambler), with minor edits by myself (see also D727, T24055).
Reviewed feature-side by @carter2422 (Jonathan Williamson).
Remove an assert in Bullet for the Character physics.

This assert happens all the time for character physics in debug mode.
In release mode, the assert is skipped but the code is still incorrect
although it does not cause any crash strangely.
BGE: fix a bug causing frequent crash on scene restart with navmesh.
Fix T41381: Moving shapes keys up/down, after last, they don't go to first (as Vertex Group).

Was more a feature request actually, but anyway...

Note this is a bit more complex than it's vgroups counterpart, since we have to handle
relations between keys (relative keys, and position for absolute ones).
Fix T41295: Rigid bodyfield weights not working.??

Looks like `rna_EffectorWeight_update()` was not really working, now uses same kind of code
as `rna_Physics_update()` from rna_scene.c.
Minor tweak to own previous shapekey_move commit.
Fix for rB3cd2c6145ae1.

ID using EffectorWeight is not always a scene...

Pretty old bug, reset flag to not use color transform by default.

Pie Menus C code backend.

This commit merges the code in the pie-menu branch.

As per decisions taken the last few days, there are no pie menus
included and there will be an official add-on including overrides of
some keys with pie menus. However, people will now be able to use the
new code in python.

Full Documentation is in http://wiki.blender.org/index.php/Dev:Ref/

Thanks:
Campbell Barton, Dalai Felinto and Ton Roosendaal for the code review
and design comments

Jonathan Williamson, Pawel Lyczkowski, Pablo Vazquez among others for
suggestions during the development.

Special Thanks to Sean Olson, for his support, suggestions, testing and
merciless bugging so that I would finish the pie menu code. Without him
we wouldn't be here. Also to the rest of the developers of the original
python add-on, Patrick Moore and Dan Eicher and finally to Matt Ebb, who
did the research and first implementation and whose code I used to get
started.
