Review request for hive, Ashutosh Chauhan and Francis Liu.

This has to do with a minor overhaul of the HCatalog notifications that we're attempting in HCATALOG-546.
It is proposed that HCatalog's notifications (on Add/Drop of Partitions) provide details to identify the affected partitions.
Using the Partition object in AddPartitionEvent, one is able to retrieve the values of the partition-keys and the name of the Table. However, the partition-keys themselves aren't available (since the Table instance isn't part of the AddPartitionEvent).
Adding the table-reference to the AddPartitionEvent and DropPartitionEvent classes will expose all the info we need. (The alternative is to query the metastore for the table's schema and use the partition-keys from there. :/)
