Add text size and keyboard settings (#38)
Settings sets the text size (100, 125 or 150 %) and the key of each
button, kept in this browser's storage and validated on load. Every font
size scales with --text-scale, and the dialogue box scrolls instead of
growing past the screen. The game screen's label, the Play message and
Help's control list name the current keys.

Screen reader announcements for every native screen and touch control
remapping remain.
