More work on Android touch events. Fixed the issues I was having with busted float coords, and added some logic for a different way to deal with selection. Doubleclicking is no longer required; instead, if you generate a finger up event within 50 pixels of where you fingered down, this will be treated as an JGE_BTN_OK event. I think this feels more natural, as you can drag around in a menu or to various cards; then when you find your selection, simply touching it again once triggers the selection.
