Directly compute polynomial features.
...
Polynomial features are computed by iterating over all combinations
of features. For each combination of features, the product of the
columns indexed by the combination is computed.
The fit method is now a no-op, and the transform method works with any
number of features (regardless of what fit was called with).

Handle_unknown option to OneHotEncoder
...
OneHotEncoder fails with a error that is not helpful if a missing
categorical feature is present during transformation.
Add handle_unknown with an "error" and an "ignore" option.

TST crank up preprocessing tests to 99% coverage
...
Fixes #3347 . (nosetests reports no missing lines, so 99% seems to
be a roundoff error, or a hint that 100% coverage is impossible :p)
