Title: Have Negation Filter    Issue #2508 

I finally managed to change it!I hope its ok!i have added the negation filter as a button in the pop up menu because i couldnt figure a way to do it in the filter Action bar. It does nothing if there is no filter selected previewsly but it negates the shown caches when a filter is selected previewsly!
