Implement origin domain matching

[airtower-luna]

Origin matching allows users to let rules apply only to requests originating from certain domains. The origin is the domain that would appear in an unmodified Referer.

The rule to apply is selected based on the length of matches in the target and origin domains as follows:

• Prefer the rule with the longest match for the target domain (as before)
• Among rules with the same length of target match use the rule with the longest origin domain match

Every rule must have a target domain, the origin domain is optional (origin match length is zero if missing).

Closes #15, closes #12.

Are you able to upload a beta version to AMO? AFAIK, only users intentionally installing a beta version on AMO will get it. Of course, you may want to confirm my AFAIK first!

I had the same thought yesterday and checked. :smile_cat: Unfortunately it looks like AMO removed the beta channel option: https://extensionworkshop.com/documentation/publish/distribute-pre-release-versions/

What I could do is get a beta version signed for self-distribution and offer it through a pre-release here, with the catch that you'd have to manually update to further beta versions. Well, unless I also set up my own update manifest, too, but that's additional maintenance effort and if I forget to remove it before release that'd be bad. :sweat_smile:

Ah, now that you mention it, I am recalling that they made that change. 😸

Another option (and one I would personally prefer), is to publish another extension called "Referer Modifier BETA" on AMO. I've seen a few other extensions do this, and it seems to be a good workaround. I can write the blurb (description) for the beta version, if that helps you.

A separate beta extension seems like a lot more trouble, both for me and people who want to test: It'd need a separate add-on ID, configuration wouldn't carry over automatically, and beta users would never automatically switch back to release, which means I'd have to maintain it indefinitely. I think I'll use self-distributed beta releases as needed, and set up an update manifest if it looks like there'll be many. Which I don't expect. :sweat_smile:

Anyway, a beta release won't happen until I merge this, which should be very soon. :slightly_smiling_face:

@wvxwxvw, if you'd like to update the RU localization before I release 1.0 let me know and I'll create an issue listing the messages that changed. If not that's fine too, no pressure. :slightly_smiling_face:

Beta release is here: https://github.com/airtower-luna/referer-mod/releases/tag/v1.0beta1

@airtower-luna I'll compare it myself.
