Major overhaul and cleanup. Support for .ubi image file installations.
Only compile&install a minimum host Gforth for bootstrapping the target Gforth, removing strange emacs-dependencies that cropped up earlier. Image file can now be built on the nanonote using 'gforth-update-image' command. Also, Gforth is now run through a wrapper that calls 'gforth-update-image' automatically, if necessary. Also first attempts at supporting libcc C-interface libraries pre-compiled on the host. Tested to compile on amd64 and i386.
