Disabled «Esc key exit» while performing backup and restore functions
Improved icons and images used in the app.
Added function to delete backup in iCloud Drive from Diary Notes (some people are not comfortable with the file/folder system on a computer. And therefore it is important to have the opportunity to do this from Diary Notes, to delete old backups in iCloud from Diary Notes).
Disabled restore and delete backup function when password is not entered.
Some small bug fixes and some updates in the documentation.
