Changes

* My two arraylist tickets I did today were put under review needs work, but I think I may disagree for the reasons, being that my patch supports everything p5 does, but doesn't support what it doesn't do, meaning, I don't support its errors, just its functionality. I can add the errors easily, but I don't think it's the right thing to do and need to get a second opinion. I spent some time today talking to Pomax about this on irc, and did some testing and thinking on it, and I still think we should allow the quirks of javascript to shine through processing.js. An example would be in p5 when you use ArrayList.set(-1, "item"); an error is thrown on the -1 not being an index, but in processing.js, the -1 becomes the second last index, which, I know is not exactly how p5 works, but why bother adding it's flaws?
