Changes regarding the dual perfect complex

We should always use \vee and not \wedge for this otherwise it might
conflict with the derived completion

A bit more about the projection formula

In particular for closed immersions it is true in general

Fix some indices

TODO: We need to change the order of some of the tensor products
in a few places to conform to the standard that

Hom(V, W) = W* \otimes V

Clean up the material from last commit

The claims on duals of pseudo-coherent complexes were too optimistic. As
a replacement we directly construct a base change map for pushforwards
of internal homs. Then we show this is a qis by the induction principle.

We also fixed the proof of the lemma on duals of perfect objects as the
previous one was nonsense.

Finally, we improve the (trivial) lemma on vanishing of Ext groups
between objects of the derived category.
