Monochrome grayscale output without extra components #45

Colors are great, but sometimes increasing the number of possible tones is preferable to changing hue. I implemented ( #46 ) a solution to display 55 (or 256 if a voltage divider is used) levels of grey, or the same number of color tones of a particular hue depending on the combination of vga channels connected to the output pin. This solution works connecting only 3 pins.

This is included in the "development" branch here and eventually it will be merged into "master".
