CvBoost train with updating

After I fixed the segfault from opencv/opencv#3193 on my PC, I faced that CvBoost doesn't do updating in the train method actually because of incorrect data_root->num_valid array (does not change the forest at all)... One more fix. After that the updating started to run. But the algorithm of updating looks strange for me. It trains new trees independently of previous ones; in prediction method it just sums values of trees from the both parts of the forest. I think this is wrong.
We should implement correct updating of CvBoost when it'll be refactored (now it's hard even to support the code).
