All angle properties were switched from degrees to radians (using PROP_ANGLE

RNA subtype), since Freestyle internally use angles in radians.
A patch set by Bastien Montagne (many thanks!)

NOTICE FOR BRANCH USERS:
This commit may break line drawing settings of already saved Freestyle files.
All angles are now treated as radians instead of degrees, so collections of
angle values might be necessary in order to recover previous visual results.
Affected properties are:
- Crease Angle in the edge detection options
- Min 2D Angle in the 'Splitting' section of a line style
- Max 2D Angle in the 'Splitting' section of a line style
- 'orientation' parameter of the Calligraphy thickness modifier
- 'angle' parameter of the PerlinNoise1D geometry modifier
- 'angle' parameter of the PerlinNoise2D geometry modifier
- 'angle' parameter of the 2DTransform geometry modifier
