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.
