Mostly typos

LaTeX: Remove useless brackets

LaTeX: \Mor

	Introduced a macro

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

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

Proof of lemma on strongly cartesian morphisms

Algebraic Stacks: Making the definition work.

	This is a rather large set of changes. It turns out that we need
	to repeat some of the work done in the setting of schemes in the
	setting of algebraic spaces. We can do this as we go along, but
	we need to have the framework in place with some example
	sections. Hence added to the project are a chapter on topologies
	on algebraic spaces and a chapter on descent and algebraic
	spaces. We further need to add much more material to the section
	on morphisms of algebraic spaces, since right now we do not even
	cover the notion of a smooth morphism of algebraic spaces.

	Of course most of this is a simple matter of pointing out the
	relevant results on schemes. Still...
