Bukkit

- Begun work on a new error reporting system. This should eliminate console and error message spamming and make bugs easier to diagnose.
- Fixed several bugs in enchantment infosigns.
- Added check to make sure that abnormal item stacks cannot be enchanted.
- Adjusted /xpinfo command to display lvl 30 instead of 50.
- Fixed bug that could occur when updating to a new version of HC

The /importsql command is not finished.  I wouldn't recommend using it.  The backups should be good for a future update, however.
The /hyperlog command is also not finished.  Don't use it yet.
