0.7.2

Screen-reader pairings tested: none yet (issue #5).
Browsers: Chromium, the whole e2e suite. A fix to the toolbar's column list; nothing breaks.

Fixed

• "Columns" stays open while columns are ticked (#101).
  Unticking one column closed the list and put the focus into the table header, because each
  tick rebuilds the grid. The list is now a panel under its button, like "+ Filter": it stays
  open across the rebuild with the focus on the ticked checkbox, and closes on Escape (focus
  back to the button), a click outside or the button. It no longer opens inline and pushes the
  toolbar aside.
