Big set of changes
Most of this is geared towards proving (in the "correct" way)
that an algebraic stack is a gerbe if and only if the inertia is
flat and locally of finite presentation over it.
Other additions are:
stackification and inertia
[U/G] ---> U/G in the case of free actions
residual gerbes are gerbes (not nec over a point!)
presentations of inertia stacks
definition free action
U ---> U/R is flat + lfp in final bootstrap theorem

Flatness of gerbes
The statement is that if X ---> Y is a morphism of algebraic
stacks such that X is a gerbe over Y, then X ---> Y is
surjective, flat, and locally of finite presentation.
There are a couple of not-completely-trivial lemmas that I added
in this commit whose proof I will add in the next couple of
commits.
