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.

Etale local on the source-and-target

	Absurdly detailed discussion of three different notions of what
	it can mean for a property of morphisms of schemes to be etale
	local on the source and target. We choose the strongest of the
	three to avoid confusion that will inevitably arise when picking
	one of the other two. Moreover, it will be nicely compatible
	with the notion (to be introduced in the next commit) of what it
	means for a property of morphisms of germs to be etale local on
	the source and target.
