Add fancier identifier for components, and a similar debug print for OperationIDKey

Warnings fix: Mark identifier() methods as const

Graphviz debugging tool now uses the node identifiers

Added methods to give useful identifiers for nodes

* All basic nodes now use an identifier string defined in DepsNode,
which gives the node type and the name of the node (if present)
* Operation nodes now report the operation opcode (human readable)
as well as the name (if present)

Remove header guards from opcodes header

Operations are now stored in the Component under a composite key (opcode + name)

The code is adapted from what is used for handling components for ID nodes

Prepare find_operation() for handling opcodes too

Doesn't work yet, but is necessary to get the code compiling

Finished porting over relationships (specifically OperationKeys) to use opcodes

Removed old defines string defines for operation names

Move opcodes enum to despgraph_types.h + modified OperationKey to use this

Replace string-based defines in node building code with opcodes where possible

* Set up proper nodes (matching the opcodes) for bones
(TODO: constraints still need to be split apart, but that'll need some eval
changes first - for later)

* A few of the unused nodes are not currently hooked up with proper opcodes
(e.g. rigidbody).

Compile fixes

Added a few more (placeholder) opcodes to make it possible to port the existing depsgraph code

Modified API's for adding operations to handle opcodes

Added back defines of "opcodes" for opearation nodes

These are essentially identifiers we can use for quickly checking or searching
for particular types of operation nodes from a component, without resorting
to dynamically building identifier strings or other crazy stuff like that.

* Unlike in the past, these are stored on the OperationDepsNodes themselves.

* Not all operations need to have an identifier defined. Only those operations
which are very common or important must have one. All others can simply
reuse the generic "DEG_OPCODE_OPERATION" with a suitable string

* These are defined in a separate header, which is designed to be used like UI_icons.h
to create a set of printable string ID's for nicer debug printing

Typo fixes, and extra comments/debug logging for tracking down armature building bugs

Placeholder debug text for DepsNodes to figure out why add_relation is failing

Code that will draw a transparent overlay of a facemap over the mesh
(crashes atm).

Improved force field effects on hair strands.

The previous calculation was modulated with the angle between the wind
direction and the segments, which leads to very oscillating behavior.

Now the formula includes an estimate for the geometric cross section
of a hair segment based on the incident angle and the hair thickness
(currently just the particle size). This gives a more stable behavior
and more realistic response to wind.

Add code that copies sorted per facemap vertex indices to a VBO buffer
