/*=========================  Version History  ==================================

1.0   -   First public release, only one site added.

1.1   -   Added SC site.
      -   Added basic func for the "unknown" sites at @include.
      -   Sites' specific code was split to separate functions.
      -   Much faster switching to darkmode (no waiting for external images/resources).
      -   Return original background in white mode.
