Fix strange behaviour of listeners

Browse Source 
Hello,

Just a couple of changes.
The change in add() will make sure a callback is never registered twice (slight change of behavior, consistent with the signals library, seems harmless to me).
The change in remove() will make sure that a listener is in the list before removing it (this one fix a bug, if indexOf == -1 then splice will remove the wrong listener).

Thanks for the hardwork !
