Fix snafu in Lemma 02W3

Thanks to Robot0079

Interestingly the text followin Defn 02W2  cautions the reader
for exactly the problem that was pointed out by Robot79!

Spell check: words starting with b, c, B, or C

move a chapter and rename a chapter

	We moved the chapter "Cohomology of Algebraic Spaces" earlier so
	we can use the results earlier in the treatment of algebraic
	spaces. Also, we finally renamed the chapter "Coherent
	Cohomology" to "Cohomology of Schemes" which is better.

Whitespace changes

LaTeX: \Spec

	Introduced the macro

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

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

Renamed fpqc-descent.tex descent.tex

Got to the point where separated etale morphisms satsify descent for
fppf coverings (not fpqc coverings though)
