Gauge improvements

[starwarsfan]

Changed the position of title and unit text on radial bargraphs. So now the unit text is located on the empty space on the bottom between the ends of the radial gauge and the title text is located right above the lcd where the unit text was located before. Additionally increased the font size a little bit for better readability. Compare screenshots:

The intention of this change was the fact, that the length of unit text is way shorter in most cases than the length of title text but the title often hits the bargraph left and right if the used text is getting longer. So I moved the unit text to the bottom and the title to the position, where the unit text was before to earn more space for the title text.
