List view from searchbar

[jannisborn]

User request:
Can you create a list view of each state? I love pennycollector.com and this list few makes it so fun to get all pennies in one state.

We could extend the functionalities of the searchbar:

• if you prepend certain tags such as loc:, title:, address:, coor: or comment you can search only in those fields
• if you hit enter you see a mapview only with the filtered items
• we then need to add a "clear view" button to return to the normal map view
