[Feature] GM State Change Persistance (#2328)

* [Feature] GM State Change Persistance

- Flymode and Invulnerable will now persist over zoning.

- Appended GMSpeed, Flymode and Invulnerable to the hideme message GMs see when they first login.

- Added #godmode [on/off] command to turn on or off hideme, flymode, gmspeed and invulnerable all in one shot.

- /becomenpc will now disable tells to the target player. It will also automatically disable GM States that interfere with its functionality.

- GM Command /toggle will not properly turn tells on/off

- GMs will now be notified if they are ignoring tells when they first zone-in, provided their GM flag is up.

- Added TellsOff variable to the output to #showstats

* [Bug] Fix tells when gmhideme is turned off.

* [Cleanup] Cleanup function and rename for consistancy.
