Unable to disable short break timer

[rmaruszewski]

It should be possible to set the duration of the short break to 0. After doing this, when the focus time is over, I should see the button "start focusing" to start the new focus session. I never do my breaks in front of the computer so I don't need the break timer at all. I just want to get notified every 25 minutes that the focus session is over. And I'd like to start the next session with a single click when I'm back at the computer.
