Change default DRF2 max depth to 20.

For a four-node, 32-core cluster on the 120M row airlines data, this
was giving approx 55 sec per tree when using the whole cluster and
about 3.5 minutes per tree for a single node (with the standard columns.)
add tooltip and hover over for points
Initialize GBM regression based on the distribution.

From R code:
 - regression (~gaussien distribution) - working response is initialized
as mean value as actual response
 - classification (~multiomial distribution) - working response is
   initialized byt 0
   - it is done when nclass>1
   - proper implementation should use bernoulli distribution for
     nclass==2 and multiomial in other cases
