Lemmas on universal effective epimorphisms

There seems to be many, many little write-ups on the web about this kind
of thing...

ell check: words starting with s, t, S, or T

Whitespace changes

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.

LaTeX: \Spec

	Introduced the macro

	\def\Spec{\mathop{\rm Spec}}

	and changed all the occurences of \text{Spec} into \Spec.

Sites: Localizing morphisms of topoi

	Realized this was missing whilst working out details on
	functoriality of small etale topoi.

Etale Cohomology: Remove the fpqc site

	Explanation can be found in the text,

Properties of Spaces: Quasi-separated spaces and fpqc topology

	A Zariski locally quasi-separated space satisfies the sheaf
	condition for the fpqc topology.

More neurotic changes

Added material on descending disjoint unions of spectra artian rings,
also added new file groupoid-schemes.tex to discuss groupoids in
schemes.
