Essentials Teleport

• Added a new server-side teleport utility plugin with /tpa, /home, /sethome, and /back.
• /tpa <player> sends a teleport-to-player request; the target responds with /tpa yes (accept) or /tpa no (deny). Requests expire after about a minute and are tracked per target.
• Successful teleports push your previous location into a history stack so /back returns you to where you were before the last teleport (and can hop between recent spots).
• /sethome stores your current world position and facing as your home; /home teleports you back there. Homes persist between restarts in a simple homes.properties file under the mod's data folder.
• Teleports use the in-game teleport component to move players (respecting world availability); feedback messages guide the player when something isn’t available (e.g., missing home or offline requester).

Notes & Limitations

• Only one pending /tpa request is kept per target player at a time; new requests overwrite older ones.
• /back history is in-memory (clears on server restart) and limited to recent locations.
• Home teleports require the stored world to be loaded; if it is unavailable, the player is informed instead of being teleported.
