The idea is to consider assemblers as "runtime" apps instead of
placing them in the "bootstrap" section of the blocks. These apps
will be used for much more than bootstrapping.
Moved its documentation to doc/asm.txt and made its code blocks
more compact.
Also, I've run VE on the TRS-80 for the first time! It doesn't work
well though. Screen is mostly blank all the time.
I removed instructions from the recipe which became obsolete when
Collapse OS became 100% bootstrapped. Also, I've updated instructions
to change the NL override which is necessary for blkup to work.
