Support for constants as internal node socket inputs.

Constants should never be linked to other nodes (will be ignored).

Added an integer type for node sockets.

Cleanup: removed unused test code.

Fix for multiplicity of internal socket mapping.

A Blender bNode input socket can represent multiple internal node inputs,
so mapping for links must use a set rather than a single socket.

First input node: getting basic properties of the "effected" point.

Complementary separate/combine nodes for vectors.

Added all the scalar math modes.

Cleanup: Separate folders for compiling nodes and for executing the resulting bvm programs.

Use a map to ensure proper links between internal nodes.

Socket names usually don't match the internal nodes exactly.

Added a topological sorting pass to make sure nodes are compiled in the right order.

Some simple math nodes to test node connections.

Test of node conversion from bNodes to internal instruction graph.

Next compiler step: convert internal node graph to opcode instructions.

init/free functions for blenvm to have a place for global initializations.

First test of the VM evaluation function.

Merge branch 'master' into mesh_samples

Create expression return values based on node tree outputs.

Invoke the BVM expression eval for effectors.

Integration of BVM into the effector system for using programmable expressions there.

Use a dedicated struct EffectorContext for storing results of effector
lookup rather than a plain ListBase.

This paves the way for future inclusion of evaluation context info in
the EffectorContext struct, and hides some of the annoying details of
the ListBase double dereferencing.
