First version of Artin's theorems
This monster commit contains the first version of Artin's
theorems on representability of stacks and spaces. It is still a
bit rough.

Getting smooth morphisms towards X
Openness of versality gives this to us. But you have to worry a
bit about (purely inseparable) residue field extensions, i.e.,
you have to show that the versality condition is preserved under
a bunch of reasonable operations.
Somehow Artin never seems to run into this problem. I think
because he consistently works with covers having a fixed residue
field. So yes, it is possible to avoid this...
