Added fully working widget and lot of other minor changes

Removed line spacing form "QUARTER" item, so tail in 'Q' is not overlapped.
Moved clock layout to separate file and it's included in main activity and widget layout.
The Clock class doesn't extend TimerTask, so clock algorithm can be run just once.
Removed dots from the icon.
