Merge pull request #1 from hwchiu/openflow-1.3

Fixed LLDP handling, DPID and OFPort serializers, accounted for default cluster ID = 0, modify circuitpusher.py for new REST API format.
Static Flow Pusher supports all OF1.3 matches and most OF1.3 actions (with the exception of masks). LoadBalancer corrected; OFFlowAdd used instead of OFFlowModify and OFPort.ZERO correct to OFPort.ANY. ActionUtils, MatchUtils, and InstructionUtils added to support static flow pusher. Strings defining flow fields *standardized* for Floodlight in the new utils classes. This means the REST API for the SFP will expect a sligthly different syntax than the current REST API (for master and 0.90). We can change the field names easily though in the utils files. These names are also referenced for the keys the SFP uses to store flow match fields and actions, just to be consistent.
