* Updated documentation
Mostly I've moved things around, cleaned up some dead paths and added more clarity.
* Cleaned up !superusers section
* Mentioning of accessibility
Recently Arch Linux shed the www portion of its site. The links still work,
but it's a 301 redirection to archlinux.org. Changed all the URL's still pointing
to www.archlinux.org to avoid the unnecessary redirection, since on browsers the 301
is usually saved and respected, but command line tools line wget or python might not
save this and always go through the redirect.
Changed README.md to not use sudo pip anymore and point users to use pacman instead.
We go into more detail on the docs. Changed binary.rst to point to the official repositories
too. Changed python.rst to point to using the official repositories for the installation of
both the archinstall script or for just installing the library (archinstall depends on python-archinstall).
