The dump_demos.m script now includes a simple oct2mat converter.  It
takes care of double quotes / single quotes, comment characters ('#'
vs. '%'), and our extended end syntax (endif, endfunction, etc.). 
This allows us to write the demos in ordinary Octave syntax.  The only
thing it doesn't handle is line continuations so those have to remain.
