Mailto is an important page, one of the many that was lost in the reorg.
Revive it as freebsd.org/contact, and move it to the legal column in the
footer. The bottom heading of mailto used to be commercial vendors, zap
that and replace it with a legal section for the freebsd foundation.
Also simplify some of the language a bit.
Adding core as a *non-blocking* reviewer so they can weigh in if they
desire, but I think this is extremely positive and reasonable and we can
keep iterating, so I do not intend to wait for them unless they ask.
