Bukkit

- Removed a few empty lines
- Implimented ExperienceManager (Formerley ExprerienceUtil)
- Fixed major flaw where bukkit thinks you have a lot more experience than you actually have.
- fixed bug where the wrong message would appear (various reasons)
- fixed bug where signs aren't fully disabled when they are meant to be.

- The config.yml will now add missing nodes (you no longer have to
delete the whole damn thing)

- Implimented xp banks.
- new permission signranks.create.xpbank
- right click to withdraw
- left click to deposit
- shift+click to transfer all
- XPbanks have limited storage and a set cost to make
- can charge money $, exp, or lvl
- new config option xpbank.cost
- new config option xpbank.storage

I have not had time to test anything yet.
