Persistence preset: RSS feeds
_Originally created by @intrigeri on [#7625 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/7625)_
It would be good to make it easy to subscribe to RSS feeds, and have the
list of subscriptions and status of feeds items (read, unread, etc.)
persistent.
The most likely option seems to use Icedove to provide this feature. If
it works out well, then we can drop Liferea. Else, we’ll have to either:
- investigate other options (e.g. the [Firefox Sage
addon](https://addons.mozilla.org/en-US/firefox/addon/sage/\))
- or go back to trying to use Liferea for this, and fix the issues
identified when we tried it the first time (tails/tails#5711 and subtasks)
