Further work on toggling

More work on toggling, some fine-adjustments (cam shake, white flash,
scale changes). Also did some fine-tuning on smoke effects to better
cover up the fact that units turn into wrecks after a long animation
plays, since rks explosions are only emitted at the start of the anim
and not at both the start and end like the default explosions.
General improvements on plane fire trails + tweaks

Added camerashake for most things, and tweaked some textures + emitters
that use them.
Fixing toggling which broke with last push

CreateFlash and CamShake apparently make it desync... ONLY stuff related
EXCLUSIVELY to the particle emission system will make it not desync.
