Automating / Scheduling offline caching

First of all thank you so much for writing this application!

I believe this might be similar to #701 , what I am proposing is an option to automatically download articles for offline viewing based on a schedule or based on connectivity to wi-fi for example. This would be immensely useful for devices that are not always online (I use an Android E-ink tablet :D )

Offline reading works just fine now, but I have to manually go to the feed or list of items and select "download articles offline"

If I had any experience with Android development I would definitely help implement this, but I can offer you my time for testing if/when this gets implemented and I would definitely donate if that helps; I rely on this app a lot :D (p.s. the "Sponsor this project" link doesn't work)

EDIT: nevermind I just saw the PayPal link, I'll post a donation soon, well deserved for this app.
