Disabled bPermissions for testing, added vault info/metadata support.

<del>Needs further testing, but it at least works with bPermissions, I've had troubles getting it to work with zPermissions, and it would be worth testing it with the default mchat info enabled as well, see if mchat -> vault -> mchat works fine.</del>

Also needs testing with the other vault chat meta supporters.

Had a wild thought as well, whether supporting the bukkit metadata system is a possibly insane idea or not.
It doesn't seem to be used much, but its worth looking into.

Edit: after the bugfix zPermissions works fine.
