Ensure player data is completely saved on shutdown.

Changed shutdown data save to synchronous (from multithreaded).  Takes
longer but guarantees all data gets saved.
New orange visualization for admin claims.

Administrative land claims now visualize using jack o lanterns - orange,
and more glow than a standard claim.
Increased effective range for claim tools.

To 100 blocks from 50.
"Too far away" with stick reverts visualizations.

Used to leave current visualization in place.  This is clearer, and
gives players a handy strategy for erasing visualizations when standing
inside a large claim - just point up at the sky and right click.
Automatic visualization reversion.

Set to 60 seconds after visualization appearance.
More accurate offline player search by name.

Will now prefer a perfect (case sensitive) match and only return a
case-insensitive match when there's no perfect match.
