[Coco] Component video for CoCo2

[Zippster]

So many projects! Awesome!  :)

Speaking of the MC-10, I’ve acquired a few of these, so an A/V board will eventually be coming from me if no one else
decides to do it.  On the MC-10 the NTSC clock for the 6847 is generated in the RF box, so that will have to
be taken into account by whoever does them (not a big deal).

One thing we'll have to do is take a page from Ed's book and run the circuit off of its own 7805 instead of tapping into the 5vdc from the mobo. There is some digital noise that gets through. Instead of building a pi filter and other stuff to filter that, it's much easier to pop a little regulator in there and be done with it.
