Scratch Extension per peabrainiac

Adds various functionalities to the scratch.mit.edu website. Current features include:

• simple & quick message viewer
• a dark theme that can be toggled on and off
• tools to make it easier to manage studios with a large amount of curators

Other features might also be added in future updates.

Any ratings and feedback as well as feature suggestions will be greatly appreciated, as it helps me decide which parts of the extension need improvement and which don't.

Note: This doesn't store any personal information like passwords or visited sites. Some details like current logins and your unread messages will be cached locally to improve performance, but won't be send to any other servers.

Also, this project is now on github - if you come across any bugs or want to request some features to be added, please open an issue there.
