as per Andrey's letter. Make a few modifications for correctness.
2. Add Language menu back to first menu - it was too buried in the
Options menu.
3. Add size information to all distributions.
4. Add a compat20 distribution (we need to make one of these!! Any takers? Please?)

Do another clean-up pass over this, making the generic menu handler much
more powerful (now handles multiple dispatch). A few more menus fleshed
out and the beginnings of the distribution handler committed. Should
be transfering full distributions over in the next commit.
