Add joda library to .classpath files.
Remove the RNG seed member from FrameTask, use a time-based seed instead.  Only used in Hogwild NN, which is not deterministic anyway.
Revert to correct naming for errors now that Python tests ignore "Error on training/valdidation data".
Change name of the option from sync_samples to mini_batch, and allow it for single-node operation.
Also add more constraints on input options.
Improve printout messages.
