Merge branch 'master' into experimental-build

added handling of vertexgroups and a fake hook system inside the FM, so passive shards can be influenced by hook modifiers via vertexgroups.

Redefinition of the meaning of "value type" for sockets (intermediate commit).

The use of "expressions" for node inputs must be generalized to support array-like
data and a level of functional programming. Inputs are now expressions *by default*.

A node can also have "variables" as inputs, which are implicitly defined in the base node
graph and should not be bounded in the first compiler step (i.e. are not defined by
pynodes). Variables instead are defined as outputs of other nodes (currently still called
"kernel" nodes), which would mostly constitute loops over such variables.

The concepts being worked on here are loosely based on those found in the Halide language
http://halide-lang.org/index.html

fixed two crashers: 1) when object had no material, that assignment failed. 2) constraints with empty meshislands crashed too

fix for passive parenting hack, it was not taken into account after transforming the object interactively

added a fake parenting for passive shards, those are simply moved with the object itself, so you can parent the entire object and have exact motion data in the passive shards

PSculpt: Autokeying Support

When autokeying is enabled, bones will automatically be keyed using the
"Whole Character" Keying Set.

TODO:
* Add support for only doing partial keying - perhaps by having options
for controlling what gets used to do this?

Code Cleanup - In preparation for some OpenGL drawing cleanups in master

Merge branch 'master' into openvdb

Cleanup.

Cycles: fix memory leaks due to hash collision.

Also clean the code a bit.

Cycles: fix crash when rendering a volume with non-uniform voxels.

forgot to take some rigidbody settings into account during object conversion

fix for possible rotation glitch when converting back to objects

fix for Fracture Modifier to object converter (external mode), not all settings were taken into account, and object disappeared when not being on startframe, but as converting mid-sim yields unexpected results, still limiting conversion to startframe, added a notification for this

added dynamic threshold adaption in case of changing timesteps for plastic constraints, also enabling plastic constraints in case they enter plastic state now

fix for windows only: avoiding changing the global locale avoids slowdown in windows string operations
