Technical lemmas on base change

Examples of diagrams of topoi for which the base change map is
automatically an isomorphism (trivial base change).

Thanks to David Hansen for several discussions.

Compare small and big etale cohomology

Terribly neurotic...

Comparing small and big etale sites

Improve the exposition and fix an error

The error was that the restriction from modules on the big etale
site of a scheme to the small etale site does not send injective
modules to injective modules. Made a counterexample. This error
does not affect anything else in the Stacks project. It occurs
in another location which we fix in the next commit.

LaTeX: \etale

Introduced the macro

\def\etale{{\acute{e}tale}}

and replaced all occurences of \acute{e}tale by \etale

Comparison

	Extremely boring comparison result between big and small sites
	of schemes and for algebraic stacks representable by algebraic
	spaces. Still preparing for a discussion of cohomology of
	quasi-coherent sheaves on algebraic stacks.
