Changed name in bootmessage from GForth to Gforth.

special SIGPIPE throw code (-2049)

-- changes to make documentation build with moofglos.fs
   rather than with mini-oof.fs (since the former contains glossary
   entries and the latter does not)

-- many small changes to glossary entries.. I think most are done
   now, so I hope to change far fewer files next time!

doc/gforth.ds

-- many, many small changes and a few large ones. Moved some sections

Minor fixes.

rebuilding documentation). Changes to .fs files and prim are restricted
to glossary (\G) additions for the documentation; this has necessitated
the addition of new white-space in places to stop the \G stuff from
obscuring the code. Many additions to doc/gforth.ds - new sections
added, a few things moved and some sections re-written slightly. There
are a set of things to tidy up before this rev. is suitable for
release, and those will be my highest priority. I have also used
"@comment TODO" to highlight other sections I plan to work on, and
added a set of comments at the start to indicate other things I plan
to modify in the medium-term.
