Detail panes: navigation as a button on top, reflowed descriptions

Open in Hints and Open in Packages were plain links at the end of the
pane, below the fold on a long one. ui.nav_button() makes them buttons,
first in the pane; the UI guideline now says navigation buttons. The
Repository description drops slack-desc's 70-column breaks.
