Fix signs in section on Cech cohomology of complexes

	The Cech complex of a complex of abelian sheaves F^* has terms

		C^p(U, F^q)

	and p is the first index. Hence the differential, according to
	our general conventions should be

		Cech differential + sign * differential of F^*

	This simplifies many of the calculations. We also added a script
	which checks the signs for the cup-product.

Whitespace changes

LaTeX: Remove useless brackets

LaTeX: Hom and SheafHom

	Introduced the macros

	\def\Hom{\mathop{\rm Hom}\nolimits}
	\def\SheafHom{\mathop{\mathcal{H}\!{\it om}}\nolimits}

	and replaced all the occurences of \text{Hom} and \textit{Hom}
	with these.

Fix fallout from changes in derived.tex

	Finally done.

Fix references and labels

	Necessary because of addition of new chapter in previous commit.
