Fix for r51447 (my CMake 2.8.9 did not like it, looks like with quotes it suites it...).

style cleanup

bmesh-decimator, skip recalculating face normals on each edge collapse. (they are not used so faster to avoid)

Cycles / OSL:
* Fix Mapping node, used wrong identifiers for Vector In/Out.

bmesh-decimate now only does CustomData_has_math for loop layers, add CustomData_has_interp() for vert & edges.

bmesh decimator support for loop & edge customdata. (most importantly UVs and vertex colors).

Add option to set object origin to the center of mass

This uses the weighted average of polygon centroids based on area
It work well in most cases but will be slightly wrong when polygons have
many vertices.

Merged changes in the trunk up to revision 51448.

fix for BM_edge_other_loop() not working right (own error in recent commit), and add new function BM_vert_step_fan_loop() for stepping around the loops of a face fan with manifold edges.

don't print mousemoves with wm_handlers_do and --debug-events

Cycles OSL: light path, texture coordinate, bump and blended box mapping now up
to date and working.

Cycles: disable motion blur for CUDA entirely now, also goes wrong on other
architectures. Still did not find a good solution.

add comment about misuse of enum set function.

Bugfix #32641

User preferences, keymap editor: it allowed to set any event for "key modifier", and not
even to NULL the option. Now it limits to keyboard events, on mouseclicks it clears,
on ESC it exits without changes.

Cycles:
* Build system fixes for closure refactor.

dont ise -Wuninitialized on gcc 4.2 and older, it gives annoying warnings.

Integer socket support in Cycles. Int values are already supported natively in OSL, but were not used as actual ints on the SVM stack. This patch implements all the necessary functionality to support reading input values from RNA properties and convert between SHADER_SOCKET_INT and other types.

switch order cmake includes warning flags so its possible to disable them

Cycles OSL: most closure code is now shared between OSL and SVM. Also fix
transmission pass and filter glossy option.

The BSDF closure class is now more similar to the SVM closures, and includes
some flags and labels that are needed to properly categorize the BSDF's for
render passes. Phong closure is gone for the moment, needs to be adapated to
the new structure still.

Cycles OSL: some build system tweaks to avoid global includes and definitions,
which ensures there is no conflict with other libraries, and avoids full rebuild
when toggling OSL on/off.
