[latexrefman] karl resignation

[Karl Berry]

I'm resigning from the latexrefman project to focus on other things.

Vincent and Jim, I made you both admins on the puszcza project so you
can do whatever.

I don't mind continuing to host https://latexref.xyz until it breaks
(it's just an svn checkout updated a few times a day, with a web
documentroot of latex2e-help-texinfo-tree/latex2e/) or until someone
wants to change it around.

Good luck to anyone and everyone interested in pursuing this.
Karl
