[Feature] Reset the pomodoro tasks

[teoh4770]

I want to have a button to reset the pomodoro completion count and unchecked the completed tasks. Why: I use the pomodoro timer every day, thus wanna start the pomodoro count fresh new.

I should name the button 'reset all' which reset the pomodoro completion count and unchecked the completed tasks.

Why? I normally have the same tasks most of the days, therefore I wanna a way to reset the progress manually with ease. Otherwise, I would have to manually reset and uncheck the completed tasks.
