Title: Undo score

- All scores can be undone (not just the last one).
- Undo button is disabled when there is no more score to undo (`canUndo` event).
- Proper feedback is displayed once undo is confirmed by server (grey falling numbers).
- Score is decreased appropriately on the Jury President's interface.

Closes #5
