Updating to the latest HBase 0.95.2

Please review this latest update. I'm reasonably happy with everything here, except for the fact that I had to add 'throws /*Replication*/Exception' to SepModel and SepModelImpl. If you know of an easier better way -- I'd love to find that out.

If not, I suggest that this gets merged into the master at some point. All the tests in both profiles pass and we will keep hacking on the 0.95.2+ side so it would be extremely nice not to diverge.

Thanks,
Roman.
