Title: add more info to rss feeds

[As requested](http://meta.discourse.org/t/rss-support-for-categories-topics/2075/68).

Additions to category RSS feed ([e.g.](http://meta.discourse.org/category/feature)):

* feed level (the category)
* `` if it's found in site settings
* ``
* item level (the topics)
* ``
* `` if it's found in site settings
* ``
* ``

I also tweaked the RSS content (``) a bit, in both feed types. Open to suggestions about what should and shouldn't be there.
