Common vector subspace operations are taking sums, intersections, and checking equality, but these are not implemented (inclusion already is). We provide generic implementations of these for objects in ModulesWithBasis and make a few other minor improvements.

Thank you, although I realized that _common_submodules needs a doctest (I forgot to add it, whoops!). I will push another change once I test, which will happen after Sage finishes upgrading.
