Weather widget prints undefined from time to time

[stickyPiston]

On production, the weather widget sometimes displays undefined, and sometimes displays the temperature. Ideally, we want to cache the results from the weather api, if it fails to fetch.

Great idea, however, what would we do if we keep failing the fetch? I would assume we would want to get notified. Maybe make old (failover) data italic, and new (regular) data none?

Hmm, strange. I wouldn't know why that happens, I'll look into it during the next commit session.

I think Sam's idea is a good one, where we make the text italic, or some other small indicator that something's gone wrong.

Now that #186 is merged, i suggest we just do the following:

• Do a number of retries before failing
• Return a fallback response with isSuccess = false on failure

We should probably just add request fallbacks in general, after coming across #160
