Adds a basic leave command. This update requires a configuration update - please add the leave command section to your configuration. You can view its format on the main plugin page.

NOTE: the "restore inventory" setting is not implemented yet! It is included in this update in order to remove the need for another configuration update when it is implemented.

/ffa leave - Return to the lobby location specified in the configuration and clear your inventory.
