Improved and extended Values
Forth 2012 Traverse-Wordlist
core: added d0= and 0= as assembly primitives
and use them in other compare operations.
Saves a lot of code space.
Wordlist entries are now 8bit clean. Words with
umlauts or e.g. Greek commands work as expected,
unless the terminal does not cooperate. Thanks to Enoch.
A few internal improvments.
