0.3.0: Fix to serious issue with playing more than one game on a table

Another pre-release build. This one should be at a point where there are no major defects remaining.

The main defect that has been fixed was one where it was impossible to play more than one game on a table (which it's unclear was present in the published 0.2.0 version, but was present in internal builds).

Otherwise, the table syncs slightly less data, has slightly less Quest workarounds (this will be revisited when we are able to do UnU testing on beta) and has slightly better desktop functionality (dropped cues on desktop return to their spawn location).
