v1.6.0-beta.2

v1.6.0-beta.2 is now marked as a release instead of a pre-release, because it currently appears to be the best-working multiplayer paint build so far.

This beta includes major changes to multiplayer paint syncing and is still being actively verified. There may still be bugs, especially in multiplayer.
