Especially after savegame load not all slots in the edicts array may be
used. Check if the current entity has a classname string. This is
another part of yquake2/yquake2#430.
This rather sophisticated command prints all entities of one or more
given classes and their coordinates. Possible classes are:
* ammo
* items
* keys
* monsters
* weapons
Classes can be combined into one command, e.g. `listentities ammo keys'
would print all ammunition and all keys. The special class `all` prints
all entities, regardless of their class.
The command is protected by `cheats 1`.
This is part of issue yquake2/yquake2#430.
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.

In RHANGAR1 the turret didn't blow up the ceiling when friendly fire
was off, because in ClientTeam() both entities were set to "" (no team),
but OnSameTeam() just did a strcmp() instead of checking this special
case (no team).
We check this now and thus it works. Hooray.
The savegame table entry for this function was invalid, but it doesn't
need to be saved anyway, so I just deleted it from the table.
