[gentoo-dev-announce] Cleanup of the "Get Gentoo" page

I'd like to suggest a cleanup of our "Get Gentoo" page. It is one of the
more important pages, because every new user has to visit it.

My main goal was to make the most important links extremely easy to
find, so I've moved the download links to the beginning of the page.

You can see the suggested page rendering here:

http://dev.gentoo.org/~phajdan.jr/where.xml

For reference, the current version:

http://www.gentoo.org/main/en/where.xml

To view the XML source of my modifications, see
<http://dev.gentoo.org/~phajdan.jr/where.xml?passthru=1>. The block I
have moved is not modified at all, so the diff should be quite clean.

What do you think?
