Fix changing focus around the main window using tab

* Override Qt's default [broken] behavior of handling Tab/Shift+Tab to navigate around the MainWindow. Completely fixes trapped focus.

* Improve handling of search results when navigating the UI.

* Fix selecting first entry after ending a search.

* Add keyboard shortcuts to directly focus on search (F1), Group List (F2), and Entry List (F3)

* Fixes #2878, #4636, and #4221
