Code review comment for lp:~gerboland/unity-2d/unity-core5-change-fix

1) Please don't ignore setting HOME_VIEW on lenses, they might not update properly if it's not set. (setting it on all lenses is fine as well).

2) It would also be nice to make sure the viewtype is set to HIDDEN when the dash is closed (optional as this point though).

3) The plain dbus call probably shouldn't be there :)
