Remove LIT< in favor of LIT" exclusively
...
This duplicated feature existed because of bootstrapping issues
with LIT", but again, with careful threading, we can clean things
up.
We can now have a proper "Collapse OS" prompt :)

pcat: move all find code in _find word

It isn't used by low level boot code anymore, so it can go there.

Refer to BOOT and (uflw) by addr in stable ABI

Was previously referred to by name+find, which was wasteful.

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.

tests: add test_sdc

The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.
