Title: trees: Min leaf cherrypick

Cherry picked the "min_leaf" parameter from PR #522 by @ndawe.
Also added a test.

I'm not sure if we should keep the "min_split" parameter, since I feel "min_leaf" makes more sense.

I know the ExtraTree paper uses "min_split" but I haven't found a reason why.

How do you feel about that? (expecialy @glouppe, @bdholt1)
