  argument types like entities, weapons and teamnames
* "burstshots", "weapon", "magcontent", "magreserve", "fragmessage" and
  "gibmessage" now allow guns to be specified by name
* "addpunct" allows plaintext arguments like "brackets" and "quotes"
* the "team" command now understands numeric teams
* entity types can now be specified by type index number
* removed some lists from the config files (now provided by listoptions)
