Title: Peformance Improvement: APIs of C4.5 and RF

Jira: MADLIB-608
For C4.5, there is no changes for the training/classification/scoring/genrules/displaying/clean.
For RF, we remove the max_split_points parameter in training API, since we doesn't need it any more.
Another change is ,that for both C4.5 and RF, we now can use an encoded table as training table.
