Bloodrink 0.2.1: fixes
First-match training now always ends, the ball no longer gets stuck and remapped controls behave as they should.

A bug-fix update, downloaded automatically by the launcher. Your saves are kept.
- Guided training: the pass step never completed, so the first match could fail to end. It completes now and, in any case, the clock restarts after four minutes.
- Dead ball: if the ball sits free and still for eight seconds (say, on a ledge in The Knot) the referee calls a restart.
- Controls: the Restart, Pause and Ball cam keys can no longer be given to other actions, and a key never ends up on two actions. The Controls page and the pause help show the keys you chose.
- Small touches to key symbols and error logging.
