Handle rate limiting #61
Description
After retrieving records for a while I usually get an exception that looks like this:
undefined is not an object (evaluating 'jsonData.items[0]')
From its behaviour, I suspect this is happening due to some kind of rate limiting at BGG. But because I can't see the actual HTTP request/response it's hard to confirm.
It'd be nice if this situation could be handled without throwing an exception. Or at least a more user-friendly one.
