Add two packages to openbox, bringign us to nb2:
- Pull in upstream's 59eb52b7c6ccbe83742e5eb8b40b5e32bb6600cc, which
  prevents windows from jumping to the current workspace when a
  net_active_window message is received.
- Change an entry in the default menu file to use the Exit action instead
  of SessionLogout, so as to not violate the POLA.
