This is pretty minor, and I'll probably get to it pretty soon myself. But it'd be good to provide the option for "centering" buttons in a TTLauncherView. Specifically I'm talking about when, for example, the layout calls for 3 buttons to a row, and the last row has only one or two. The layout should automatically determine that the incomplete row exists, and center-justify the buttons. If you only have one, put it dead-center, under the middle button of the previous button. If you you have two leftover buttons, lay them out so that there is equal space to the left, center, and right of the buttons. Right now, the buttons are left-justified, and I think the look is a little sloppy.

Does this make sense? Not sure if I've explained this clearly. Like I said, I'll probably take a crack at it myself, as I'd like to clean my layout up in my app.
