The Stacks project

chern -> Chern and noetherian -> Noetherian

Thanks to Lor Gro

Added a new chapter

We moved the later part of the chapter on \'etale cohomology
to a later spot in the Stacks project because this will be needed
in order to make sure there are no forward references later on.

By the way, currently there are 3 forward references which we will
fix soon.

Final in series nuerotic edits

D_c(X, R) and D_{ctf}(X, R) for etale topology

Just the basics

Making sure we have a proof environment for every statement

Tags: Added new tags

	Mainly new tags for lemmas/propositions/theorems in the chapter
	on etale cohomology.

Etale Cohomology: More edits

	Coding style...

Etale Cohomology: More edits

	Coding style...

Etale Cohomology: White space changes only

Etale Cohomology: Lots of edits

	One of the problems is that the coding style is completely
	different and nonuniform. Another is that there is a lot of
	material for which it will not be possible to find proofs
	internally in the stacks project for a long time. Perhaps we
	need to introduce a way of indicating this in the document.

	A better solution is perhaps to add only those parts to the
	actual stacks book published on the web which mesh well with
	the stacks project.
