No difference between right anchor and right separator

Currently there is no difference between trailing `^` and `|` characters on network rules, e.g. the parsed version fo the `||gateway.reddit.com|` rule from EasyPrivacy is indistinguishable from a hypothetical `||gateway.reddit.com^` rule.

A request to `https://gateway.reddit.com/example.html` should be allowed by the first rule and blocked by the second. Currently both rules block this request.
