Performance: Claim Lookup

Major perf improvement for claim search.
Version to 8.1.9
Performance: Claim Lookup 2

Another big performance boost for claim lookup, and a reduction to the
number of player interact events processed by the plugin.
Version to 8.2
Added command alias "claimlist"

Some players forget the S.
Fixed players charged blocks twice for same claim.

Side effect: likely faster plugin boot due to reduced number of reads
and writes.
Version to 8.2.1
UUID Migration Rework, Bug Fixes

Using multi-faceted strategy to better resolve UUIDs, and do it faster.
Fixed dispensers putting fluids in a neighboring claim.
Automatically deleting claims for worlds which no longer exist.
Streamlined visualization code, hopefully will reduce or eliminate weird
visualizations for VERY big land claims.
Removed option to disallow un-claiming land in creative mode.
Better default for last login date for new players or players who've had
their data deleted or lost.
Version to 8.2.2
Faster "trust" family commands.

Accomplished by NOT searching offline players except for /untrust.
Now UUID-migrating players with $ and _ names.

Players with names starting with these special characters will now be
migrated.
Memory footprint: Claims Lookup

Eliminated unwanted chunk loads from claim lookups and boot process.
Also a slight perf improvement for claim lookup.
Memory Footprint: UUID Conversion

Saving RAM by clearing data after it's no longer needed by UUID
conversion code.
Performance: Faster player name lookup.

Especially beneficial to /trustlist and error messages (like trying to
do something in a land claim without permission).
UUID Migration Perf Tweak

Another minor tweak to save time.
Version to 8.2.3
BugFix: Now really converting $/_ players in flat file mode.

Missed one of two filters the first time.
Fixed log errors related to visualizations.

Can't measure distance when A and B are in different worlds.
Perf boost for first-time logins.
Perf boost for banned logout.

Banned players no longer have their data saved on logout.
