Title: refs #23: use NSURLConnection for network tile fetches

This uses `NSURLConnection` for tile fetches, with a timeout equal to the desired compositing wait time divided by the number of retries that will be performed, so as to not exceed the desired wait time. It does not solve the problem of an ultimately failed download, however.
