Added the ability to define the ip and computer id for a manual ban (in the banning panel). This is so mirroring bans or banning people who were not online during the round in progress does not require admins to spawn a mob, set their variables and then ban the mob.

If however an admin attempts to add a manual ban for a player who was present during the current round, a player who still has a mob somewhere in the game world, the proc will prioritize the mob's ip and computer id variables, not the things entered in the banning panel form.

Manual bans (banning panel) allow you to define an ip and computer id.
