Spigot bug:
http://www.spigotmc.org/threads/one-right-click-player-interaction-fires-two-player-interact-events.37600/#post-431325
Version to 9.2.1
Removed debug message.
Fixed /deletealladminclaims NPE.

I think this has been broken since the beginning of the UUID migration
work, and nobody noticed.
Armor stands are now buildable in creative worlds.
Better in-game sign notifications.

Multi-line, and including the sign's location.
Fixed /deletealladminclaims NPE (really).
Fixed NPE in vehicle damage handler.

Ugh, more stupid shit - if it's a vehicle damage event, how can there be
no vehicle associated?
Version to 9.2.2
Added death drop locks, removed /deathblow.
Fixed spam related to minecart damage.

For real this time, I hope.  :)
Added adverts for /ac and /acb.

So people who don't read the manual will stop asking me already.  :)
Limited fire protection to claims-enabled worlds.
Version to 9.3
Added retry logic to UUID migration.

Finally got a detailed log from hitting a rate limit - added retry logic
for only the cases where it's definitely a rate limit problem.
Fixed disappearing subdivisions.

Was happening on both resize and on extend downward.
Added config options for eavesdropping.
Added config options for eavesdropping. (2)
Code cleanup.

No functional changes.
