* Updated documentation
Mostly I've moved things around, cleaned up some dead paths and added more clarity.
* Cleaned up !superusers section
* Mentioning of accessibility
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).
