Fix Bug 631 and enhance 601: Handle multiple keys (pressed, released, types incl. auto-repeat)

- Using keyCode (bit) maps to isPressed and isAutoRepeat, allowing use of multiple keys

- Enhance unit test TestKeyEventOrderNEWT w/ injecting variations of 2 diff. keys

- Manual tested on X11, Windows and OSX w/ and w/o auto-repeat
