Conventions: plain chrome, and how a move is made

From feedback on Waving Hands' BoardGameGeek thread: no label-and-colon
lines or abstract headings around the game; histories read oldest
first; the move and its button stay together and in view; warn before
a wasted move rather than after; let a move be typed.
