Restructure compilation order so as to not have any
label jumps larger than 256 words.

Also fix add not adding
Clean up builtin_words
Add user defined words
Add working word lookup
Make latest point to compile time link
Working return stack and toin read/write
Add interpret_loop
Add reading word by word

I believe it is working as intended, but I
still need to make sure with further testing.

Commit before implementing assembler
Finish line input
Add fill instruction and finish line reading
