Default theme Casper v3

[allamiro]

Any plans to update the theme to Casper v3 look and feel ?

@jekyller This is much needed. Casper 3 looks very nice when compared to casper 2. There doesn't seem to be much layout difference too

Agreed, the floating header would be a major UX upgrade, and it'd be awesome to have Casper 3's support for OS-level Dark Mode.

Version 4 is already out! I will try and add jasper4 version whenever I have some more time, but anyone can try ;)

After reading this and using Jasper2 I created https://github.com/Agraphie/kaschber which is based on Casper v5. I hope it's ok to post this here, otherwise let me know then I'll delete. In any case, feedback & contributions welcome!

@Agraphie Great stuff!
