Openflow 1.3

Fixed the build issues many were having. Still need to change the javadoc version to 1.7 in the build.xml file (will be fixed in next commit). Static flow pusher supports all OF1.3 matches; tested with addFlow() from the static flow pusher service. REST API pushing not tested yet, but should theoretically work. I'd like to test the REST API, but I think people would like to not have build issues, so I'm proposing this commit now instead.

FYI -- whether a switch treats OFPort.ANY different from OFPort.NONE is an implementation issue.  I don't know what OFPort.Zero is ;-(  Where did that come from ...
