Portals

Have a confirmed report of the plugin working, I'm assuming it's good, if anyone has problems with it please submit a ticket.
The portal message should now be configurable and can be completely removed if desired (I would appreciate it if someone could test this)

bug where player can potentially fall through world or get stuck in blocks
getting stuck between two way portals
(neither of these have been confirmed on recent patches and may have been internally fixed, but nothing has been done by me to address them)
