Various minor bug fixes / enhancements

* Fix issues when Config options were renamed
* Fix compile issues when using clang 10
* Rearrange database menu icons and import database menu icons
* Set minimum size of MainWindow to 800 to prevent search bar from hiding
* Fix not saving password generator options when closing the standalone generator
* Add headers to health check reports
* Don't show hidden content dots when notes are hidden but empty.

* Fix saving new database files in SMB shares on Windows, fixes #4809

* Gracefully handle duplicate attachments :
Instead of bailing out with an error, prepend a random string to the name of duplicate attachment records. This prevents data loss from other programs that mishandled KDBX XML writing. Fixes #2493

* Properly handle blocked import of signed KeeShare database, fixes #4413
