Instead of just extracting the state itself, we'll also fetch the reason
(typically parenthesis-enclosed) and use the rest of the header as
additional data, which is only shown if the extrainfo preference has
been turned on.
The current code only shows the basic auth status and a description of
what it means. Some users (i.e., me) would like to see more information,
typically the whole header part that is responsible for the decision, so
prepare to show this information.
This commit does NOT hook it up just yet. This will be done in a later
commit.
Auth data needs only be processed once and is independent from the
actual route data.
This has the added benefit that auth data, which is entirely local, is
shown even if the API returned an error.
Currently, on error (rate limit, unable to reach Mailhops API), an error
message is shown and all additional information is bypassed.
This also means that the theme is not being applied.
Change the code to show local data even in error cases, and also apply
the theme option.
Actually, links containing a comma character are just multiple links,
the current code wants to fetch the first element and drop all others.
We'll change this at a later time, but for now, just fix the bug at
hand.
