2e9e7047bf Make INTERPRET break on ASCII EOT 
This should allow me to simplify LOAD's exit mechanism on block
end.

33d37d4ce9 WORD: don't overwrite RAM on words over 31 chars 
This allows me to reclaim some RAM I hadn't even noticed I
needlessly monopolise.

9b85961093 Rename "Core words" to "XPACKed core" 
Now that this section is so small, I think I can see a possibility
for cross-compiling Collapse OS entirely, which would be great
because we could get rid of the relinker.

dfe474ca0e xcomp: add XCOMPILE and X[COMPILE] 
This allows us to move words like ABORT" to xcomp-core, which is
I think the last roadblock before being able to unify all drivers
into a single xcomp layer.

1094ec9c57 Make DO..LOOP stable 
DO and LOOP now only compile words from stable ABI, which make them
suitable for xcomp. This will greatly simplify driver writing and
allow us to mostly avoid the low/high divide in drivers.

LEAVE is still xcomp-incompatible though.

This make us very very tight for "<0x100" limit for literal words.
Hopefully, we won't need more stuff in that area of the binary...

73482e7ea1 Reword root block 
Usage of "LIST" wasn't explicit enough for a complete newcomer. I
hope that with this wording, anyone can figure out how to navigate
blocks and learn the system.

06a4674317 ti84: implement a-lock 
There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.

2f1e635b9d ti84: tidy up driver code 
Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.

Gave more priority to CPU in the emulator because initialization would
