Adds support for preserving animations on region crossings and TPs.

Known issue: after TP, the self client doesn't see the animations going, but others can see them. So there's a bug there (TPs only, crossings seem to be all fine).
Untested: did not test animation overriders; only tested playing animations from the viewer.
