Merge remote-tracking branch 'refs/remotes/origin/master' into fracture_modifier

Conflicts:
source/blender/editors/physics/CMakeLists.txt

explaining comment: "need to distinguish between mesh and non-mesh objects for fracture modifier" and quiet some warnings

removed unnecessary conversion from radians to degrees (internally) and using degrees just in the UI

replaced rigidbody count function (avoiding 3 different loops over rigidbodies) and quiet some warnings

cleanup: automatic code styling with uncrustify_clean.sh

Calculate blending weights for preview hairs by constructing a kd-tree
of simulated hairs and using nearest neighbors.

Removed debug prints.

Solved various update issues with the hair preview factor.

This is still terribly messy, especially because every change of the
particle system has to be piped through the dummy cloth modifier somehow.
The automatic caching system also tends to get in the way a lot; after
changing the preview factor one basically always has to start at frame 1
currently because the cloth modifier has to be reconstructed and forgets
about all caching.

Widgets:

* Add option for shaded/non shaded widgets
* Normalize arrow widget size to 1.0 so size is predictable. Probably
will use the same scheme for other widgets as well

closed some memory leaks when calculating shard mass and after fracture (C++ cell struct)

Revert "Squashed commit of 'temp_custom_loop_normals' branch."

This reverts commit 6b2952ca3d848b8d663ad092c27980f919969990.

Squashed commit of 'temp_custom_loop_normals' branch.

Merge branch 'master' into testbuild

All translation axis now drawn and operated through the widget system.

Merge branch 'master' into temp_custom_loop_normals

More fixes...

* Manipulator Y 3D arrow moved and rotated correctly.
* Light manipulator doing undo now
* Scons should be fixed.

Green widget handles y translation properly.

ManipulatorGroup customdata.

Make WidgetGroup data private.
