Better handling invertible modules
Of course an invertible module should be defined as a module such that
tensoring with it is a self-equivalence on the category of modules. This
doesn't change a thing beyong the definition, because we usually are
working on locally ringed spaces or topoi where an invertible module is
the same thing as a locally free module of rank 1.

LaTeX: Hom and SheafHom
Introduced the macros
\def\Hom{\mathop{\rm Hom}\nolimits}
\def\SheafHom{\mathop{\mathcal{H}\!{\it om}}\nolimits}
and replaced all the occurences of \text{Hom} and \textit{Hom}
with these.
