Improve chapter on hypercoverings

Made it more general so it works also for the hypercoverings exactly as
defined in Verdier's original.

LaTeX: \Ob

	Introduced a macro

	\def\Ob{\mathop{\rm Ob}\nolimits}

	and replaced any occurence of \text{Ob}( with \Ob(. There are
	still some occurences of \text{Ob} but these are sets, not the
	operator that takes the set of objects of a category.

LaTeX: uniformize notation
