Minor Updates in collaboration with @Haruki1707
- Now the updater works asynchronously (which leads the program to open faster on poor connections)
- New GUI when updating
- Indicator of download status
- No program stutter if connection is lost while downloading
- MOST IMPORTANT keeps old version if new version is not downloaded
- Unblur the background image as a preparation for multi-background suggested by shawn#1002 from Discord.
