Farewell-Flag if you teleport away

WORLDGUARD-3512 - Reported by LordRazen

This isn't a bug but a suggestion:
If you teleport out of a region with a farewell-flag you get the farewell-flag. But from my experience, this isnt necessary in most of the cases. The farewell-flag is usefull if you pass the border, but if you port outside you dont care anyway and the messages could confuse.

So my wish is simple: reconsider if it's necessary to show the farewell-flag if you teleport outside or if you can add an option to hide this or if it's even possible to do any changes at this point.
