Example bash client does not handle new batch query results JSON

[CodingDoug]

With batch query rules JSON from #33, the example yields errors like this:

$ ./examples/http/client.sh localhost:8080

sqld> select * from foo

jtbl:  Cannot represent this part of the JSON Object as a table.
       (Could be an Element, an Array, or Null data instead of an Object):
       [ ... JSON here ... ]
