Whitespace changes

LaTeX: \Sh

	Introduced the macro

	\def\Sh{\mathop{\textit{Sh}}\nolimits}

	and replaced all occurences of \textit{Sh} with \Sh.

LaTeX: \Mor

	Introduced a macro

	\def\Mor{\mathop{\rm Mor}\nolimits}

	and replaced all the occurences of \text{Mor} with \Mor.

LaTeX: \Sch

	Introduced a new macro

	\def\Sch{\textit{Sch}}

	and replaced all the occurences of \textit{Sch} with \Sch.

Fallout from error fixed in previous commit.

	Most of the fixes were in the more abstract part of the stacks
	project. As a by product the chapter on topologies of schemes
	has been slightly improved.

Etale Cohomology: Local rings and henselization

	Tying the etale local ring to the strict henselization of the
	"usual" local ring. Mainly just fluff.

	What is missing in the section on henselian local rings in the
	algebra chapter is a better characterization of the (strict)
	henselization, or rather, it has to be stated and proved that
	the defining properties characterize the henselization.

Sites-Cohomology: Torsors and H^1
