ConfigurO 2.6

Fixes

• The window can be dragged by its title bar. It never could: the bar is a child
  window and was consuming the press itself, so the window could only be moved
  by maximising it. Snapping and the drag-to-edge zones work too.
• Card titles no longer run into the line beneath them. Every card on every
  screen shares one control, so Settings, Network, Apps and the rest all showed
  it — most visibly in the about box, where the name, description and licence
  line were drawn on top of one another.
• The Integrator screen no longer writes an error to the log every time it
  opens. Checking whether "Take ownership" is installed threw whenever it was
  not, which is the normal case.
