moved the runRF/RFView polling for RFView completion out of h2o_cmd.py (old legacy) into h2o.py like other algos.

Since RFView can be called independently of RF (unlike the completion of other algos), it's slightly different.
(RFScore is meant to replace the use of RFview like that. added runRFScore and random_forest_score, which call random_forest_view)
updated some test lists
