Added a QTextEdit for art descriptions.
Also added the ability to save and load them from the database. Changing of the description field also triggers a unsaved changes prompt.
Implemented the last remaining tag in the TagSelectDialog to be automatically selected when confirming the dialog.
Improved logging of DB connection and selected tags
Fixed a bug where imported tags were not considered if they were implied by any other tag in the whole database.
Also made the image author link clickable and open the URL with QDesktopServices
Fixed a bug where editing the alias or implication of a tag caused a crash.
Also changed titles that were left unedited from the file name to stay empty inside the database and not be filled with the filename
