RSS from content is broken

[teemu]

When looking for the RSS of the content page, link:

http://lemill.net/acl_users/credentials_cookie_auth/login_form?came_from=http%3A//lemill.net/content/RSS

the system asks you to "login" - in both cases; you are login or anonymous user.

Ok. I see that on lemill.net but ...

It seems to be working here on my instance.

I suppose that should be checked on lemill.net itself then we'll be able to get the log for that.

(In [1508]) Tests for RSS-feeds. Currently 3 of 4 fails. Refs #1248, refs #1226, refs #88. RSS-feeds for group blogs are not included if they're going to be changed into forums.

This is weird. At lemill.net/content/RSS still gives this error, but at local instance with fresh copy of lemill.net:s Data.fs it works. Something we've done after 1.8.1 has fixed it, but cannot really say what it could have been.

Somehow one obj_item in rss_template.pt is wonky and fails to have even absolute_url. As this bad obj_item cannot be reproduced, I'll fix this template to ignore obj_item if it is this bad.

(In [1523]) Fixed #1248, but there is still work to be done with RSS. Currently topic-rss:s do not support limiting results by search terms, so you cannot for example have a RSS-feed for content/tags?tags=learning. search_rss.pt can do this, so I'll move some tricks from there to here.
