Cleanup: Internal degrees removal.

This patch changes most of the reamining degrees usage in internal code into radians.
I let a few which I know off asside, for reasons explained below - and I'm not sure to have found out all of them.

WARNING: this introduces forward incompatibility, which means files saved from this version won't open 100% correctly
         in previous versions (a few angle properties would use radians values as degrees...).

Details:
- Data:
-- Lamp.spotsize: Game engine exposed this setting in degrees, to not break the API here I kept it as such
                  (using getter/setter functions), still using radians internally.
-- Mesh.smoothresh: Didn't touch to this one, as we will hopefully replace it completely by loop normals currently in dev.

- Modifiers:
-- EdgeSplitModifierData.split_angle, BevelModifierData.bevel_angle: Done.

- Postprocessing:
-- WipeVars.angle (sequencer's effect), NodeBokehImage.angle, NodeBoxMask.rotation, NodeEllipseMask.rotation: Done.

- BGE:
-- bConstraintActuator: Orientation type done (the minloc[0] & maxloc[0] cases). Did not touch to 'limit location' type,
                        it can also limit rotation, but it exposes through RNA the same limit_min/limit_max, which hence
                        can be either distance or angle values, depending on the mode. Will leave this to BGE team.
-- bSoundActuator.cone_outer_angle_3d, bSoundActuator.cone_inner_angle_3d: Done (note I kept degrees in BGE itself,
                                                                           as it seems this is the expected value here...).
-- bRadarSensor.angle: Done.
