Add regex support to whitelists

This modifies the whitelist and https forcing code to internally use
unix extended regular expressions to match domains.  The old config
syntax converted to an appropiate regular expression.  Inputing of raw
regular expressions is possible by prepending the string "re:" in
front of a regular expression, for example:

js_wl = re:^(.*\.)*cyphertite\.com$

would be the same as

js_wl = .cyphertite.com
