therefore also the values of LATEST and HERE).

Fix bugs from round 1 of debugging
...
There were several issues I ran into immediately:
- The cold start was pointing to the dictionary entry of QUIT instead
of the CFA
- The RSP needed to be set before calling QUIT, as DOCOL uses the
return stack
- I'd forgotten LITs before values in a couple of places
- I'd not accounted for LITs in several branch offsets
- A few dictionary links were wrong
