Towards trace map on de Rham complexes

This is an intermediate commit because there is now a
rather large set of changes already... but it is not quite
done yet.

The Tate map

Found a way to prove a global isomorphism

det(L_{Y/X}) ---> omega_{Y/X}

for lqf lci morphisms of locally Noetherian schemes where in the proof
you NEVER have to change coordinates. The key is to find suitable versal
deformations and realize that the isomorphism is clearly unique for
etale morphisms... The idea for this comes from the paper by Garel cited
in the section.
