Locally quasi-finite morphisms
It actually takes a fair amount of work to esthablish good
properties of the definition. The whole notion is intimately
related to the notion of quasi-DM morphisms of algebraic stacks.

Permance of flat morphisms
Case of algebraic stacks... This is not the whole story but it
is what we need now for the discussion of gerbes. I'm sure we'll
have to pay later for our rash decision to add these simple
cases here explicitly now:)

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.
