Title: ENH: train_size and test_size in ShuffleSplit (#721)

#721

* I have deprecated arguments test_fraction and train_fraction in ShuffleSplit and train_test_split and renamed them to test_size and train_size.
* I have also modified documentation and tests (added one more to test deprecation warning).
* I had to rewrite the argument checking a little to take in account that these values can now be integers.

The deprecation warning is: "test_fraction is deprecated in 0.11, use test_size instead." Is it correct? I am not sure which version should be there.
