RCON Steam ID ban only works when the player is connected

When a Steam ID is used, RCON bans should work regardless of whether the player is connected. Currently admins are prevented from easily banning one player from all of their servers simultaneously; they must resort to editing Bans.json or playing whack-a-mole with an obtrusive user.

This is the RCON response observed when the player is not in the server (Steam ID redacted):

permban 00000000000000000
Could not find player matching "00000000000000000"
