Groupoids: Started writing about finite flat groupoids

	Immediate goal: help prove facts on points of algebraic spaces
	More gloabl goal: towards finite flat quotients in category of
		algebraic spaces

Collection of small changes

	Small addition in algebra.tex
	Invariant opens, representable quotients in groupoids
	Finite monomorphism of schemes is closed immersion
	Separation axioms added to spaces-properties
	Morphism between algebraic spaces is representable by algebraic
		spaces
