Fix UV face dot refresh when toggling sync-select

Cleanup: localize creator.c definitions

As creator.c is used for the 'main' function,
avoid obscure declarations being placed so prominently.

- Move Blender as a Python module declarations into it's own section.
- Move USD declaration to an 'extern' just before it's called.

Cleanup: OCIO: Remove extern "C" around blender headers

Particles: support custom particle events in solver

Previously, there were only particle-birth and time-step events.
Now the solver can handle custom events. On the user level
this does not change anything yet. This feature of the solver
will be used by an upcoming Age Reached Event node and
possibly others. When this node exists, I can finally remove
the hardcoded maximum particle age.

Fix error in recent rename

This function is defined outside of Blender.

Cleanup: spelling (initialized)

Cleanup: use term init instead of initialize/initialise

The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
