forth: remove 0 and 1 constants
...
They do save space (nearly 100b), but they complicate our Forth-ification

forth: make word name of variable length
...
This allows us to save a whole 500 bytes on the final binary size!
This change comes after I took a look at the hex dump and saw that one letter
constants in z80a.fs took a lot of space.

forth: make "(entry)" call WORD itself
...
Otherwise, when a defining word would be called outside a definition
itself, it would get the name of the last parsed word, that is,
itself!
