Merge bitcoin-core/gui#317: Add Direction column to Peers Tab

6971e790c32253ecddb6108e796afd3892ced7fe gui: add Direction column to peers tab (Jon Atack)

Pull request description:

  Picking up #289

  This adds a `Direction column`, making the peers tab the same as the `Direction/Type` row in the peer details and the direction and type columns in our other user-facing peer connections table in `-netinfo`.

  Users can now sort the peers table by direction. The default sort is set to inbound, then outbound.
