Changing favorites list to link to landing pages instead of bottom iframe.
Hiding favorites iframe.

It shouldn't be necessary since the links that triggers it is altered, but on rare occations
it seems to show up anyway? (and I'm not even sure if the display isn't set on element - in which
case this fix won't work)
Changed landingpage from favorites from fn=search => fn=display

This removes the bottom "results" and next/previous buttons.
Hiding [Back to Results] button from full view pages if and only if the referrer is favorites.

If you come from a favorites link, you don't wanna go "back" to a resultListing.
Reverting 8d1148a. Turns out 874e3ef also fixes the problem, since fn=display has no back to results button.

We might wanna consider adding a [Back to Favorites] button instead? (that's why I have kept the solution in the log)
