Fix key leak, re-enable NN JUnit test.
Use the same tie-breaking for scoring in NeuralNet as for NN.
Don't print the comment for disabled arguments.
Cleanup locking/unlocking, deletion of NN.
Remove JUnit test.
Improve input handling for GUI.
Update JunitRunnerDebug to run on 1 node, which allows all the NN JUnit tests
to pass (now that the tie breaking is the same again).
Note: multi-VM modes differ (must be a conflict between single-threaded
execution of old NeuralNet with multi-node DKV)
Merge branch 'arno-deeplearning2'
