Merge bitcoin-core/gui#311: Peers Window rename 'Peer id' to 'Peer'

657b33e qt: add translator comments for peers table columns (Jarol Rodriguez)
73a91c6 gui: rename "Peer Id" to "Peer" in tab column and details area (Jon Atack)

Pull request description:

  Picking up bitcoin-core/gui#290

  **Original PR Description:**
  - renames the peers tab column header from `Peer Id` to `Peer` to allow resizing the column more tightly (this will be particularly useful after #256) and does the same for the peer details area.

  While here, we also add Qt translator comments for the Peer Table columns.
