UI improvement: Friends in the same restaurant

[tuomasnurminen]

The number of friends on the main page eating at the same place should be a link to a new page which has a list of friends eating in the same place. The view on the main page should not show those eating at the same place, but those eating some elsewhere, as you are able to see those in the same place through the link "5 friends". Also, the text "lunch with you" needs to be removed.
