Bumped version of floodlight using to expose floodlight's link discovery.
Registered for switch status handler to listen to link discovery service.
Constructing _InternalPort ralph objects when receive a switch updated
message during link discovery.  Still must pass these into ralph
switch so that can register them there.
Wrapping port update messages in ralph and pushing them into ralph code.
Ralph code actually adds new ports to each switch.  Additionally, had
an incorrect condition that I was checking in
SingleHostSwitchStatusHandler.  This condition meant that I was adding
ports when I wasn't supposed to be. Fixed.
Removing dead code.
