Add after create callback

[sbrunner]

[sbrunner]

Existing before_create is passed obj=None, so docstring is a bit messy ("..., and the database object to be updated").

The object is not always None, an object is passed if we send an ID!

Updated :-)

Ok so this is not a create nor insert, it is an update

We could discuss about what to do in such case, but it not the subject of this PR.

Should we call before_update in such case ?

before_update already exists for object update :-) before_insert with the code you propose (I modified it a little bit by removing the unneeded create variable), it looks correct :-)
