If you try to use the teleporter and the teleport was rejected for any reason (like having a nuclear disk), you won't get the chance to get a random damage from the teleport.
Fixes issue #2236.
Removed some spawn() calls.
Removed the chance of fail from the portal effects (the blue portals made with hand teleporters).
The portal datums will now return 0 if the teleport failed, and now use a new proc, start(), instead of New() to handle themselves.
Standarized teleport.dm from the helper_datums folder.
Removed the checks for centcomm z level and away missions z level for teleports. Now you can go there.
changed the /red messages from the teleports datum to span classes.
The "[something] bounces off of the portal!" were replaced for "The portal rejects [something]".
Removed an extra "the" on those messages.
