Generalize section on infinitesimal deformations
We want to use the definitions even when the base scheme is not
necessarily Noetherian.
We also removed the requirement in (RS*) that the affine schemes in
question map into an affine open of the base scheme. This is never
needed when one actually verifies a given stack has (RS*) and in
fact this more general notion is always a consequence of the
original restricted one.

Excise finite type conditions
We need to have the functors T_x and Inf_x for all modules not just
for finite type ones. This actually simplifies the discussion a
tiny bit as we don't have to carry along the finite type conditions
everywhere.
Thanks to David Rydh for pointing this out (see
commit 2ccbbe3087e4dc2b1df2193c81ede7486931424c for more
information).

Dual obstruction theory
Construction of the element in H^1(K \otimes NL) as explained on
the blog here:
http://math.columbia.edu/~dejong/wordpress/?p=2514
Next, we turn this into a map and apply the previous results.
This we should be able to use for lots of cases, but it will
certainly not cover all cases.
