byte addressess

I'm loosing too much time about byte/word addressess.  The original
idea was to use only word addressess to make the assembler simpler,
but that's inconvenient in Forth if there is also to be byte data

Let's keep the assembler as is, but make the change at the interaction

The problem seems to be in the function "tfind" that treats code and
data the same.  This needs to be split into two functions: find-code
and find-data :: symbol -> byte.ptr

These then should be defined in the toplevel namespace so the
interaction code can pick them up there.
