Enhance Tags / Saved Searches

* Rename "Database Tags" to "Searches and Tags"
* Separate searching for all entries and resetting the search
* Support selecting multiple tags to search against
* Fix using escaped quotes in search terms
* Make tag searching more precise
* Support `is:expired-#` to search for entries expiring within # days. Exclude recycled entries from expired search.
* Don't list tags from entries that are recycled
* Force hide tag auto-completion menu when tag editing widget is hidden. On rare occasions the focus out signal is not called when the tag view is hidden (entry edit is closed), this resolves that problem.
* Remove spaces from before and after tags to prevent seemingly duplicate tags from being created.
* Also fix some awkward signal/slot dances that were setup over time with the entry view and preview widget.

Allow changing tags for multiple entries through context menu

* Closes #8277 - show context menu with currently available tags in database and checks those that are set on one or more selected entries. When a tag is selected it is either set or unset on all entries depending on its checked state.

* Add ability to save searches and recall them from the "Searches and Tags" view
* Add ability to remove a tag from all entries from the "Searches and Tags" view
* Cleanup tag handling and widgets
