Can't View Queries With Completely Numeric Hash

If a query's hash is hex encoded but all numeric i.e. "9752952652010367" the query is not viewable since the code assumes it is a base 10 integer and skips decoding it as hex. The code should probably be checked to make sure that query hashes are always sent to the client as hex so it can always safely decode it as hex when retrieved for a GET var.
