remove python requirement from main page, moving to downloads page

There was some discussion of this on mercurial at selenic.com, but with no
consensus.  Since none of the leading binary packages on the web site
(unix-like distros excepted) require a separate Python installation, I
preferred the idea of simply not mentioning the requirement at the main
page.  I've moved it to the downloads page, which allows us to explicate
a bit more as well.
