Adds integration and function mirroring of Essentials
- Warps are now imported as needed from Essentials on load (if installed).
- Default messages for warps have been altered to mirror Essentials. (still configurable)
- New warps created with RocketTeleport are added to Essentials to allow Sign warps to function (sign warps will not rocket). Also allows RT to be uninstalled without losing the new warps, but I hope you don't do that.
- New warps created will now include yaw and pitch (the direction your looking at the time the setwarp command is used)
- NOTE: Permissions for warp commands are still unique to RocketTeleport. RT will not use Essentials command perms.
