Added ignored buttons, like volume change or switch app.
Bumped to version 0.0.5.dev
Changed onKyeEvent to work call super when ignores keys are pressed
Added code to call button_down and button_up events.
Changed array = [] to array.clear in several places to avoid garbage collection.
Input events list are now deleted after calling window.update.
So button_down? on window.update will return true if a button was pressed.
