Virgil Dupras 91f79d1131 Move z80a from B200 to B5
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.

when you use them, you're expected to write the offset
afterwards yourself. )
