fixing "load"

Problem: 'load doesn't mix with 'expand.

There is a simple fix for this: make 'load behave as a preprocessor
only, which means it is a reserved word that cannot occur anywhere
else in the source code.  Maybe this is a bit restrictive though..

It's probably simpler to flatten the current recursive calls for load.

Now.. Do I really need the current-load-relative-directory parameter?
I'm not using 'load anywhere.. It's probably OK to dump info in the
forth search path parameter.

Hmm.. let's quick-fix it for now built on existing structure: the
first item in the forth path will be the current directory.  This is
simply changed on begin/end of a loaded sequence.

Better: abstract the value of forth-path to include both current
directory and search path.

OK. it seems to work.

There's one thing that's going to bite me later though: the mode
(macro/forth) isn't saved..  Maybe this should be implemented as
parse-time state also?  Just have a single struct that can be easily
dumped as an abstract transformer?

Anyways..
Road is open to do it properly + it should now be possible to use
'require inside 'load -ed files.
