* - url_rss (default: false)
*
* POST request adds a feed in database.
* Parameters are:
* - url_rss (default: false)
* - category (default: false)
* - new_category (required if category == 'nc')
* - http_user (default: false)
* - http_pass (default: false)
* It tries to get website information from RSS feed.
* If no category is given, feed is added to the default one.
*
* If url_rss is false, nothing happened.
