Name fix

Stubbing in code to create eval nodes for curve datablock

Copying over old particles depsgraph building code

Cleaned up clarifying comments for structure of graph setup for particles

Stubs for particle systems graph building

Added handling for particle system animation

NOTE: this does not really work out that well if a particle block is
used in more than one place...

Typo fixes in comments

Added defines for list+number of all operation nodes to depsgraph

The purpose of these defines at toplevel is so that operations
over the nodes do not necessarily require setting up a full
aparatus for performing node traversal.

Also, the nodecount variable provides us with a valuable ability
to cross-check whether all nodes have been evaluated. (Then again,
it doesn't quite work, as not all nodes will be scheduled up)

First stab at higher-level querying API - Get list of ID-blocks with links to/from self

Convenience wrapper for finding nodes from RNA Ptr+Prop -> Used for node tagging calls

Remove obsolete comments

Removed questionable motiontracker rel, and noted what it does (according to Sergey)

Removed unused section divider

Fixed DEG_add_operation() function definition to match new apis

Ported over node type logic to new API's

Notes for group graph building

Ported over all DEG_get_node() calls in building code to new API

Added note/stub for sound system updates on frame change

Pass "main db" pointer down to scene building function

Added include header for more types
