Implement proper persistence of the following prim properties:

Floating text, Rotation, Texture animation, Particle System
This will make "Eye Candy" scripts work without modification in
XEngine. The use of the CHANGED_REGION_RESTART hack is no longer
needed. Implemented in MySQL only, hovertext also in SQLite.
