This patch 
- allows the now playing widget to automatically size text when the widget is sized. The sizing is a function of height with some of the width also causing teh text to size.
- makes the play controls slighty bigger and easier to press
- Adds some margins to all the controls
- makes the progress bar a bit fatter
- Removed the "by" and "on" text

Tested with some really long tracks like "Counting bodies like sheep with the rythm of the war drum" to see if sizing would work. Tested it on 22" monitor and on 32" television. Sized it to fill each screen horizontally and fill the screen half way vertically.
