Title: Fixes #3288 "WP7 border-radius CSS performance issue" via changing listv...

I was experimenting with styles and found out that removing 'position: relative' style for list elements (li and all internal divs) resolves performance problem. In this case dialog and all elements are rendered correctly and I don't see any lags.
All changes are part of listview CSS only and shouldn't affect other components. Also I don't see any places where we change positioning via top/left/etc properties. Per my tests all browsers render list view exactly the same.
