[HTTPS-E Rulesets] Improved rule for archive.org

[Ralf Muehlen]

Our Wayback Machine cannot do https, so it should be excluded in
src/chrome/content/rules/Internet-Archive.xml:

<ruleset name="Internet Archive">

        <target host="archive.org" />
        <target host="*.archive.org" />
        <target host="*.us.archive.org" />

        <securecookie host="^\.archive\.org$" name=".*" />

        <exclusion pattern="^http://web\.archive\.org/" />

        <rule from="^http://((?:\w+)\.us\.|www\.)?archive\.org/"
                to="https://$1archive.org/" />

</ruleset>

Thanks,
