Force https for resources from the current website

[Salamandar]

For instance, cppreference.com has hard-coded
<link rel="stylesheet" href="http://en.cppreference.com/mwiki/load.php?debug=false&amp;lang=en&amp;modules=ext.gadget.ColiruCompiler%2CMathJax%7Cext.rtlcite%7Cmediawiki.legacy.commonPrint%2Cshared%7Cskins.cppreference2&amp;only=styles&amp;skin=cppreference2&amp;*" />
That http request seems blocked (no CSS is loaded), but that'd be better to detect that's the same domain and redirect to http.
