559ffe4a23 Particles: Added particle flags for tracking state (one-time triggers, etc)
Also removed some older effects that weren't interesting, improved others,
cleaned up the unused functions in several, and renamed most of them to
reflect which feature they're demonstrating.

9a8b846baf Particles: Sub-effect spawning and some slight refactoring
* Added a new binding type, SkEffectBinding. This stores another
  entire effect params structure (so the JSON is just nested).
  The name is a callable value that spawns a new instance of
  that effect, inheriting the parameters of the spawning effect
  or particle (depending on which kind of script made the call).
* Broke up the monolithic update function into some helpers,
  got some code reuse with the script calling logic.
* Unlike particle capacity, there is no upper limit on child
  effects (yet), so it's easy to trigger runaway memory and
  CPU consumption. Be careful.
* Added death scripts to effects and particles, which are a
  common place to want to spawn sub-effects. Like spawn,
  these run on each loop, but for one-shots they play at the
  end. Even with loops, this is helpful for timing sub-effects
  (see fireworks2.json).
* Finally, added a much more comprehensive example effect,
  raincloud.json. This includes a total of three effects, to
  generate a cloud, raindrops, and splashes when those drops
  hit "the ground".
