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.
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
Made the predicted url in TagImportDialog clickable and open the url in a browser with QDesktopServices.
Also fixed the source url in window.py to use QDesktopServices
Upgraded dependencies and noticed a breaking change in pyqt5 (QMainWindow.move() requires integer parameters). Fixed it and introduced minimal versions in requirements.txt
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
