Use `UpdateAllowUnknown' for non-model related parameter. (#4961) 
* Use `UpdateAllowUnknown' for non-model related parameter.

6f16f0ef58 Use bst_float consistently throughout (#1824) 
* Fix various typos

* Add override to functions that are overridden

gcc gives warnings about functions that are being overridden by not
being marked as oveirridden. This fixes it.

* Use bst_float consistently

Use bst_float for all the variables that involve weight,
leaf value, gradient, hessian, gain, loss_chg, predictions,
base_margin, feature values.

In some cases, when due to additions and so on the value can
take a larger value, double is used.

This ensures that type conversions are minimal and reduces loss of
precision.

c8ae52f17a add scikit-learn v0.18 compatibility (#1636) 
* add scikit-learn v0.18 compatibility

import KFold & StratifiedKFold from sklearn.model_selection instead of sklearn.cross_validation

* change DeprecationWarning to ImportError

DeprecationWarning isn't an exception, so it should work the other way around.
