Documentation: Clearer structure on front page

Divides 'User Guide' topics into different kinds of users, End Users,
Project Owners / Power Users and Administrators. This is the first
change in a coming series that will rework the structure of the
documentation.

This will probably make new users feel more welcomed, as they won't
have to see the most advanced topics to begin with.
