The usage instructions were showing review request URLs off the root of
the site, rather than ones from a Local Site. We now generate a URL (and
a sample ID, for consistency) and send it off to the template for
rendering.

There's also a fix for some non-localized usage text ("Or:").

Tested each of these services both with and without Local Sites.
