Update dependencies for Rust and Admin interface.

- Updated Rust deps and one small change regarding chrono
- Updated bootstrap 5 css
- Updated datatables
- Replaced identicon.js with jdenticon.
  identicon.js is unmaintained ( https://github.com/stewartlord/identicon.js/issues/52 )
  The icon's are very different, but nice. It also doesn't need custom
  code to find and update the icons our selfs.
