This makes future refactoring easier, since the elements will
retain their borders even if the hierarchy changes.
Also round some maps and the legale section since I think those now
look nicer.
Now that all uses of the images and thumbnails have been migrated
to flex grids, we can remove the margin and padding from the original
css classes and revert to using them.
Based on https://stackoverflow.com/a/31732902 this ensure that when
a secondary action list wraps the additional lines don't start with
an item delimiter by pushing it to the left, outside of a parent nav
element which then hides it.
This opens up many possibilities for more interesting things to be
shown on the dashboard, as well as making it easier to find if
you have lots of content in your profile.
