Number of input columns is published by generated model.
Generated model simplifies mapping from enums to integers.

Flag to DRF2 for building everything on one node

Default is based on whether or not the data fits on one node (very crude
notion of "fits"), but should "by default" run one node for small data.
Does not use a whole ton of one-node optimizations; does not run
tree-building on other nodes
doesn't seem like the 'error' number in kmeans2 is calculated right
Generated models improved:

 - sample of data moved into separated class since it was poluting
   constant pool of generated model
 - h2o-model.jar is now published by H2O web server
 - comments about downloading h2o-model.jar
Change copy_data to build_tree_per_node
Fixed Frame.anyVec() bug. A newly copied frame may have inherited _col0 pointing to old vector.
