[broadway] Report most special keys in keypressed

Browse Source 
Some special key keycode values as seen in keydown actually match
normal keys (like "." has a keyCode 46 on keyPress, which is the same
as Delete, but 190 for KeyDown). So we must match the special keys on
keypress. However, some things must be checked on keydown as they are not
generating keypress events.
