added support for TVout on G100-G400 via add-in daughterboards. Note: MGA_TVO (maven) revB requires more tweaks than MGA_TVO rev C. Both differ from G400 maven timing wise. I'll probably work my way down: first fix RevC, then rev B. add-in boards work just as good (or bad) as G100/G200 'standard' TVout boards now. RevC chips work better than revB chips. Both fixable to math G400 and later, I hope. Bumped version to 0.31
