Add a new command 'teleport'.

Browse source 
A command that teleports the player to abitrary locations was often
requested and may be helpfull for debugging, so finally add it. It works
like a normal teleporter: It moves the player to the requested location,
clears all movements, tells the server and clients that the entity just
teleported and telefrags everything that's in the target location.

The implementation does not verify if the requested location is save,
the player may teleport into the world model or even the void. But the
requested Z coordinate is elevated by 10 units to prevent the player
getting stuck in the floor.

The command is protected by sv_cheats.

This is part of issue #430.
