Add ability to show penalty times

[marc-white]

Penalty times are an important part of floorball. The system should be able to:

• Hold and display the remaining penalty time against a given player number/initials;
• Only display actively running penalties (only two bench penalties per team can be measured at once, and only one bench penalty per player at once);
• There must be a separate button to 'queue' penalties, and then 'start' all queued penalties (penalties do not commence until the game resumes, but the clock may keep running during the down time);
• Penalty time is synchronized to game time (i.e. penalty time must start/stop with the main game clock)
