new complete_match/get_victim functions to clean up code for role commands

also !roles/!gamestats/!fgame accept partial names now

almost every role has been tested, shouldn't be any major bugs probably
this is wrong, allwolves is defined as var.list_players(var.WOLF**TEAM**_ROLES). This change would make it so wolves can figure out who cultist/minion are by attempting to kill them.
