Re-write of eqn(7) parser and MathML output.

This adds parser-level support for the grammar described by the eqn
second-edition technical paper, "Typesetting Mathematics — User's Guide"
(Kernighan, Cherry).
The reason for this re-write is the grouping rules, which were not
possible given the existing implementation.
The re-write has also considerably simplified the HTML (and, if it ever
is completed, terminal) front-end.
