A little GUI cleanup and perhaps a progress bar

Hi, some ideas to make pomodairo a little more appealing (and friendly to 
smaller screens).

1) The app could be made less tall in the digital clock area (about 1/3 of 
unused space there). 
2) The "New Task" and "Next" button could go next to the "Menu" button".
3) Center the digital clock.
4) Make a progress bar behind the digital clock.
5) Make the digital clock a little less tall (about 3/4 of current height)
