Improve RSS support

[lsmith77]

I read all my news inside my RSS reader (I use Newsify on iOS but the proposed solution should work with any RSS reader). As such I currently rely on services without a paywall (though I happily pay for The Guardian and Taz).

So as a paying Republik customer I would like to have a custom RSS feed URL, that would contain pre-authenticated links to articles. This means if I open the article on my RSS reader, the URL would “log me in” to Republik and so the RSS reader would be able to open the article, so I can read directly in my RSS reader.

Note technically the pre-authenticated URL should just do the login and then redirect to a non pre-authenticated URL, so that when I share the URL of the article, I would not leak the pre-authenticated URL but the normal public URL.

Potentially in that case optionally the RSS feed should already contain the entire content of the articles, to make it easier to read offline and to just include the public URL as the reference, to further reduce the chance of leaking the pre-authenticated URL.

I would also be fine if the pre-authenticated URL would only work 2-3 times to again prevent the risk of people free-loading off of accidentally pre-authenticated URLs.

Of course the token added to the URLs to handle the pre-authentication should be specific to each article.

If this feature would be provided, I would happily subscribe again to Republik.
