Bukkit

v1.7.1
Fixed little bug in startup. This version will not dump a stacktrace if you use an incompatible version of craftbukkit.

v1.7
Added support for ProtocolLib (optional)
If you happen to have ProtocolLib it'll now work fine with TagAPI. No changes required either way.

v1.5
Fix for armor bug.

v1.4.1
Moved spammy messages to debug mode (enable by setting config.yml debug: true

1.3.1 support
YOU MUST BE RUNNING BUKKIT 1.3.1 FOR THIS

v1.3.1
Fixes a problem where players would lose tags on respawn.
Should warn you if it starts up on a 1.3 server to update (An update will be required)

v1.2
Important bug fix if you use any plugin with this that isn't VanishNoPacket

v1.1
Implement refresh methods, for plugin developers to force your name tag to update
Cleaned up a ton of static methods nobody but me should have been using.

Fix an NPE I stupidly didn't fix last time. ^_^

Fix some NPEs.
Changed some logging from WARNING to FINE for debug purposes.
