Structure: roles and features

Bengfort requested to merge structure-roles-features into master

My idea is to have two sections in the beginning, one on high-level features and one on roles. Both then cross reference the relevant step-by-step guides for each entry.

I kept large parts of the existing guides, but also changed quite a bit. I still need to clean up these changes.

Fixes #16 (closed)
