Merge #179: Add Type column to peers window, update peer details name/tooltip

be4cf48 gui: update to "Direction/Type" peer details name/tooltip (Jon Atack)
1518883 gui: add "Type" column to Peers main window (Jon Atack)
6fc72bd gui: allow ConnectionTypeToQString to prepend direction optionally (Jon Atack)

Pull request description:

  This pull:

  - adds a sortable `Type` column to the GUI Peers tab window
  - updates the peer details row to `Direction/Type`, so the `Type` column without a direction makes sense (the tooltip is also updated)
