Added /epointso (epoints override)

Allows users with the permission "epoints.override" to set their own
points to give to players instead of the preset amount in the config.
e.g
/epoints {player name} - sends preset points from config
/epointso {playername} {points} - send the amount of points you said in
the {points} part of the command

Alias: /epo {player name} {points}
