Merge branch 'rss-viewer'. This is the biggest feature I've attempted to add for quite a long time. Quite a lot of refactoring of the HTTP client and threadpool has been done (to make it not send session tokens etc), uploads (was too much code duplication), and the add dialog was done to implement this. Don't expect this to be some fully automatable RSS client, use something like flexget for that, this is just a simple view on RSS feeds. It uses the rss-glib library, which you will probably need to install yourself to optionally use this feature. There are probably bugs still, so report them.
