Include a global timer so client can track session time. Could be used to try to beat previous session completion time.

There is a stopwatch function in the exercises now but it needs to go higher than 5 minutes, count upwards and have a 10 sec coundown. And the time when you stop it should be displayed so it can be entered into the workout.
Now it is finally possible to set rest period higher than 5 minutes so I can use those for longer AMRAPs
