Fixed OF10 aggr stats ROFL issue. Added translator support for a few more stats types. Stats are generally working now. No known issues. There is an issue with general stability - ROFL brings down the whole program without error reports after about 6-10 minutes. A large set of unrequited OFPT_ECHO_REQUEST messages build up (40 or more) and then Floodlight reports "IO Error: Connection reset by peer".  No exception, no error, just silent program termination.
