A lot of internal changes. Config system has been mostly rewritten to avoid having to resolve config strings all the time.

Added economy support.

Added proper world support each with permissions

Reimplemented the queue system.

Fixed some minor bugs

Added a bunch of commands for ease of use.
/rtp addworld <world>
/rtp removeworld <world>

/rtp resetcooldown <player>
/rtp setprice <price>

(setting the price to 0 will disable economy)

Vault is required if you want to use the economy features

Added a whole bunch of permissions to go with the new commands (check the plugin page for a full list)

Updated the config so its recommended to let it regenerate and copy your settings over.
