Improvement ideas

[STK123]

Few ideas to improve Nine Men's Morris experience:
- show my colour. Useful in turn based games. Sometimes you forget what is your colour, and it is not obvious when looking at the board
- highlight last move. Useful in turn based games. I know this can be seen in messages showing coordinates, but visual clue might be more helpful
- show number of played and remaining pieces

Thanks.

Highlight last move would be a great addition, Connect4 does this really well and it's very helpful,
Replaying the last move(s) takes too long.
