Please Dont remove regex from blacklist when corresponding site is added to whitelist

[mike-tn]

When I use regex in blacklist and add a site, matching the regex, to whitelist, the regex is removed from blacklist.

Example:

1. I add /.*/ to blacklist
2. then trying to open some http-only site and click "Back to HTTPS (add to whitelist)" button
3. the site is added to whitelist but /.*/ is removed from blacklist

I think it would be better to allow contradictory addresses in whitelist and blacklist, with whitelist in priority.
