Range limited teleporting

[alaestor]

Long Range option at Teleport console should be range limited

I propose:

• [x] user toggle for range limitation

not going to implement (seems a bit pointless)

• [] local teleport:

  • [] user toggle & configurable: Local teleport range limit
  • [] TeleportTargeter interface support
  • [] TeleportBehavior implementation

• [x] global teleport:

  • [x] user toggle & configurable: global teleport range limit
  • [x] TeleportTargeter interface support
  • [x] TeleportBehavior implementation

decided not to implement local targetting range; seems a bit pointless.
