[DISCUSSION] Add Caching for feeds

[rickyphewitt]

Placeholder issue to discuss and consider caching the feed xml files.

Things to consider:

• Does caching the feeds make sense
• How long to cache
• What feeds to cache
• Should this be a user configurable setting (default on/off)

I'm not sure caching makes sense for feeds as it has the probability to introduce more issues than benefits.

Reason I'm adding it as an issue:

• Caching has been mentioned in other issues
• I have seen random url timouts when requesting feeds
• If a user is browsing the app, selecting a show multiple times should not re-download the feed as (most likely) nothing has changed

Feel free to chime in :)

Possibly cache feeds to <10 minutes so that browsing experience is quick, but we still have recent content.
