Possible bug

Hi!!

First of all, congratulations for this amazing project ;)

I was watching your code and maybe I found a bug. Excuse me if I was wrong.

In SpriteCanvasView.js, everytime you activate SelectColorProto and SelectAreaProto, you push in _listeners array a new listener, but this array has never been cleared. Maybe you have to clear it or initialize the array evertime you call activate.

I repeat, excuse me if I'm wrong

this may be the cause of large ram usage. xD
