Bug fixes:
- The navigation bar follows the app's dark theme
- Darts: the third dart and the opponent's throws stay readable, and every dart shows its score
- Dark theme: buttons and selected options are easier to read
Improvements:
- Blackjack: cards are dealt from a shoe and turn over
- Minesweeper: flags drop in, mines go off one by one, and a cleared board waves
- Checkers: optional capture
- Profile: the version and commit link to GitHub
