PC now hits $0000. Likely a bug.

Adds text colour register.
Oddly this isn't currently being set. So probably another latent fault elsewhere.

Completes logic for pixel framing. Well, mostly; this doesn't yet allow for auxiliary-using II modes being off to the left.
The perceived effect though is that a frame appears and then freezes. So a clocking issue may still be afoot.

Nothing is there.
