Significant improvements to the Auto-Type select dialog. Reduce stale and unnecessary code paths.
* Close select dialog when databases are locked.
* Close open modal dialogs prior to showing the Auto-Type select dialog to prevent interference.
* Never perform Auto-Type on the KeePassXC window.
* Only filter match list based on Group, Title, and Username column data (ie, ignore sequence column)
* Always show the sequence column (revert feature)
* Show selection dialog if there are no matches to allow for a database search
* Close#3630 - Allow typing {USERNAME} and {PASSWORD} from selection dialog (right-click menu).
* Close#429 - Ability to search open databases for an entry from the Auto-Type selection dialog.
* Fix#5361 - Default size of selection dialog doesn't cut off matches
* Clean up parent alignment code
* Don't hide widget if it currently has focus
* Use Qt::Tool window type on macOS as well. This prevents the popup help from hiding to the background if the main window has focus.
* Fixes#2814
This allows `t:word` instead of `title:word` and `p:word` instead of `password:word`, and so on. The rule is that an abbreviated name expands to the first field name that starts with it, with exceptions
`u:` expanding to `username:` instead of `url:` and `pw:` expanding to `password:`.
* Support ! modifier (same as '-')
* Create reusable PopupHelpWidget as self-contained popup that can
be positioned around a parent widget and will follow the movement
and sizing of the window
* Eliminated KEEPASSXC_MAIN_WINDOW macro and replaced with
getMainWindow() function
* Add tests to cover search help show/hide
