Clear cached file sync credentials/URLs when changing settings
Automatically retry intermittent Amazon S3 upload timeouts

"Your socket connection to the server was not read from or written to
within the timeout period."

I can't reproduce these reliably, so this is fairly untested, but it
seems to work. It backs off exponentially when the error occurs, and
halves the delay on successful requests.

Eventually all 50x file sync errors should also be retried
automatically, but that can't really happen in 4.0.
Don't hang file sync on network errors

Network errors (where the connection itself failed, rather than failed
HTTP requests) were being thrown directly in the stream listener, which
prevented the Zotero.Sync.Storage.Request -- and therefore the file sync
-- from ever completing.
