Algebraic stacks: Deligne-Mumford with trivial inertia is a space

	To prove this for a general algebraic stack we will first prove
	a characterization of a DM stack as an algebraic stack whose
	inertia is formally unramified, or equivalently diagonal is
	formally unramified. Before we do this it makes sense to change
	the notion of unramified as suggested by David Rydh (see
	documentation/todo-list).

	We also added the proof of the statement that the property of
	being an algebraic stack is invariant under equivalences.
