Added operators that include validities in comparisons

[ritchie46]

This PR adds equality kernels that allow you to include validities in comparisons. Rationale for this is to be able to have the same behavior as numpy:

>>> np.array([1.0, np.nan, 2.0]) == np.array([1.0, 1.0, 2.0])
array([ True, False,  True])

The default kernels propagate the null values and would return [true, null, true].
