The Stacks project

Fix typo

Comparison

	Extremely boring comparison result between big and small sites
	of schemes and for algebraic stacks representable by algebraic
	spaces. Still preparing for a discussion of cohomology of
	quasi-coherent sheaves on algebraic stacks.

LaTeX: Remove useless brackets

LaTeX: \Sh

	Introduced the macro

	\def\Sh{\mathop{\textit{Sh}}\nolimits}

	and replaced all occurences of \textit{Sh} with \Sh.

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: \Mor

	Introduced a macro

	\def\Mor{\mathop{\rm Mor}\nolimits}

	and replaced all the occurences of \text{Mor} with \Mor.

Fix more references

	Final fix for now

Spaces and change of partial universe

	Slight improvement of existing material.
