Fixed merging issue
Fixed tests. Layout for filterBar now uses only two constants and animates a constant instead of adding and removing a bunch of constraints all the time.
Added cancel button to icon selection view
Extracted context bar for trash, history and filter browsing. Some regressions in focus handling were introduced. History tab will go away as this will be incorporated in the entry comparable to searching. Code cleanup. Moved copying to KeePassKit
