Ton Roosendaal 7130ab3fe6 Bugfixes 4082 4112 4172 4232 
Each report was about a different failure with Particles, all related to
weak handling of animation systems and the depsgraph.

Fix has 2 parts; depsgraph now signals "object recalc" to be for time
changes; this then is used to bypass particle-building (since that's baked).

Other part is better object caching while makig particles.
