[Console] Swap j and k key's behavior to fit vim mode

There is a problem in the Deluge's Console UI. This UI supports the j
and k keys as up and down, but for some reason they are inverted. This
commit inverts back the behaviour of j and k in several places.

Resolves: https://dev.deluge-torrent.org/ticket/3483
Closes: https://github.com/deluge-torrent/deluge/pull/377
