Manual add of time breaks

[soloam]

The new addition of break times is great and solves a problem I've always had with tracking breaks.

It would be nice to also have the option to add break times manually. At the moment, as far as I can see, it's only possible to add a break by starting the timer.

Being able to manually enter a break, just like a regular time entry, would be really useful, especially when you forget to start the break timer at the time.
