Comment:
Going all the way to the splitting field was causing some slow
performance, so I've reworked it to manage the fields directly. This
includes special casing finite fields and managing the embeddings as well.
it should be noted that a simple error in
projective_morphism.conjugation() was corrected in this ticket as well as
a simple error in affine_morphism.homogenize()
The new version is ready for review now.
