Fix for bug ONOS-897:

Add support for specifying flow entry priority.
Now the default priority is 32768 (same as NOX)

The priority can be specified by add_flow.py script with the
"priority <flowPriority>" keyword.

	src/test/java/net/onrc/onos/ofcontroller/util/FlowPathTest.java

NOTE: The conflicts in file FlowDatabaseOperation.java and FlowPusher.java
have been resolved by hand.
The rest of the conflicts are because of missing test files and have been
ignored.
