Fix error raising

[jaymzh]

Currently if you get a 429 (or any other we theoretically catch), we won't catch it because we're doing string comparisons on integers, and thus we jsut get a JSON::ParserError.

This fixes that so we get the expected error classes.

In addition it adds a new unknown exception that gives the use some extra information.
