Misc Updates and favicon fixes (#5993)

- Updated crates
- Switched to rustls instead of native-tls
  Some dependency were already using rustls by default or without option.
  By removing native-tls we also have just one way of working here.

Updated favicon fetching which now is able to fetch more icons.
- Use rustls instead of native-tls
  This seems to work better, probably because of tls sniffing
- Use different user-agent and added several other headers
- Added SVG support. SVG Images will be sanitized first before stored or presented.
  Also, a special CSP for images will be sent to prevent scripts etc.. from SVG images.
