[macOS][iOS]: Add automatic episode download option

[gdavis]

As a user, I would like to be able to mark certain podcasts so they always download new episodes added to the feed.

Derived from user feedback:

thanks for your nice Mac-Podcast-App. Is there any chance you will include automatic downloads for episodes (Preferences —> Podcasts —> Download episodes —> then new option: when feed refreshed or something like that)? I would highly appreciate that. Or is there option new episodes got downloaded without any other action needed (pushing to queue) I didn’t recognize yet? Greetings from Germany

Dev tasks:

• [x] Update PodcastSettings with a bool for tracking if automatic downloads are enabled

• [x] Add a mechanism for triggering new downloads when podcasts are added. Post notification from import feeds? Have an FRC looking for episodes with the podcast setting enabled and no file?

• [x] Sync setting in iCloud

• [x] Add control to the podcast settings UI

  • [x] iOS
  • [x] macOS

• [x] Add summary cell with total number of files and size

  • [x] Include delete all button to remove all downloaded files

• [x] Fix disappearing search bar on macOS.

Moving this up in priority. One of the most requested features atm

The work for this feature, as well as adding new download views to manage your downloads for both platforms, has been completed. This will be available for testing in version 1.1 (available soonish).
