Bukkit

- added reload command
- default setting now have colored messages
- fixed something that might have caused issues with player names
- doesn't display Null when player isn't in a group (still not sure if it actually works with no groups, might depend on your permissions plugin)

- sometimes? creates new empty line in data file on server restart
- get the config right ! I might add in checks for it because if you get something wrong Vault will give you tons of errors.
