Avro Schema Swap

                 Key: CASSANDRA-1351
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Stu Hood
            Assignee: Stu Hood
            Priority: Critical
             Fix For: 0.7.0
         Attachments: 0001-Specify-the-readers-schema-as-different-from-the-wri.patch

Due to misreading Avro's docs, I swapped the Schema parameters to Avro's schema resolver.

The schema resolver allows for backwards compatibility by accepting a writer's (ser.) and
reader's (deser.) schema, and resolving them to determine which fields to add or ignore. The
reader's schema was not being set correctly, which was breaking backwards compatibility (although
not the disk format).
