Cycles: Avoid using lookup table for Beckmann slopes on GPU

This patch is based on some work done in D788 and re-formulation from Beckmann
implementation in OpenShadingLanguage.

Skipping texture lookup helps a lot on GPUs where it's more expensive to access
texture memory than to do some extra calculation in threads.

CPU code still uses lookup-table based approach since this seems to be still
faster (at least on computers i've got access to).

This change gives about 2% speedup on BMW scene with GTX560TI.

Cycles: Remove unused Beckmann slope sampling code

It did not preserve stratification too well and lookup-table approach was
working much better. There are now also some more interesting forumlation
from Wenzel and OpenShadingLanguage which should work better than old code.

Fix T44251 (2nd try): Changing views using numpad broken

BGE: Fix T36703: Character motion actuator local movement not working correct.

The character motion actuator local movement does not taking account of the object rotation.
It is necessary to rotate the motion vector before adding the local movement.

For KM_ANY I've filtered out every event that has a click type, although
that was only needed for the additional event sent on KM_HOLD. A bit weird
that this only happened on a few machines though.
