z80: move boot code around
...
Bring native words together, make the next/exec/does/compiled
cluster be at the beginning.
Next step: bring find code into _find word.

z80a: make mnemonic names more uniform across assemblers
...
Initially, I used the same letters as those used in the z80 ref
docs, but it makes the different assemblers harder to use than they
should. Having consistent "argtype" rules across assemblers should
help.

Refer to BOOT and (uflw) by addr in stable ABI
...
Was previously referred to by name+find, which was wasteful.

confusing.

VE: add 't'
...
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

Make string length-prefixed instead of null-terminated
...
I'm not sure why I chose null-terminated initially. Probably because
the z80asm version had null-terminated strings.
Length-prefixes strings are the traditional form of strings in Forth
and it's a bit easier to work with them with traditional forth words
when they're under this form.
