Modified getRegionInfo call to return region compaction state if requested.
Added a method to HBaseAdmin to show a table's compaction state.
Table UI is updated to show the table's compaction state too.
TestCompactionState is green.

Checked the table UI in live cluster, and it does show the proper compaction state now.

Changed the test a little to handle the failure Ted saw.  I could not reproduce it, which makes it a little harder.
