A documentation link in the sidebar, and the footer points home

Documentation above Settings, opening in a new tab — the docs are read beside
the work, not instead of it. The footer's "Fluksio - <year>" links to
fluksio.com; the sidebar logo deliberately keeps going Home, since navigating a
running installation away to a marketing page is not what pressing it means.
