removal of mpfnmark

[Robin Fairbairns]

the package macros/latex/contrib/other/mpfnmark seemed to offer
interesting functionality, but unfortunately had a bug that meant that
in many cases it simply didn't work.  the author has not responded to
suggestions that the bug be mended.  i therefore added a working
version of the functionality to the latest version of footmisc
(macros/latex/contrib/supported/footmisc), some time ago.

the ctan team has now decided that the mpfnmark package itself should
be removed; it will disappear from mirrors over the next few days.

users should switch to using footmisc, instead.
