Website Content - Update

[Lucas Rocha <lucasr gnome org>]

Hi all,

So, I've spent some time today doing lots of cleanups in the website.
It seems Claus updated some drafts from the wiki (Claus, confirm?).
What I did:

- Updated all links in the footer to point to real stuff
- Updated all urls to match the planned structure
- Created default pages for all sections
- Updated About section with content from wiki
- Added "Why choose GNOME?" page in products/desktop/why

For those who are editing content, there are some content-related bugs
that I'd like to know if they are still useful in some way. If not,
let's just close them. Here they are:

https://bugzilla.gnome.org/show_bug.cgi?id=463509
https://bugzilla.gnome.org/show_bug.cgi?id=463512
https://bugzilla.gnome.org/show_bug.cgi?id=463728
https://bugzilla.gnome.org/show_bug.cgi?id=463736
https://bugzilla.gnome.org/show_bug.cgi?id=463746
https://bugzilla.gnome.org/show_bug.cgi?id=463509

Claus, could you please add me as developer of the website product in Bugzilla?

That's all for now. Cheers!
