Changes:
NEW: implement aop command (player permissions + console use)
NEW: implement reload option (player permissions + console use)
CHANGED: remove redundant check on notify... now ops get it by default.
CHANGED: relocated opblock check to be inside the listener.  It was the only way to get the toggle to turn on/off with just a config reload :(
CHANGED: Since isOp() was removed from check above I set aop.notify to op default (rather than false)
