Update README.md to demonstrate user creation

[boscoMW]

Create use step was skipped in the orm demonstration, this update reflects that.

Thanks! :)

For reference, User.objects.create(...) creates an unusable user (no password and has is_staff=False so it can't connect to the admin).

I don't remember the order of the chapters but if the admin chapter comes after this one then we might run into problems.

@bmispelon This user is created with the purpose of using it when creating a Post instance.I've not encountered it further in the tutorial.What you might be referring to is the admin user which is created later.

@mbosco You're right (there's been some change in the order of chapters and I haven't kept up with it).

My worry was that the attendee would try and create an admin user later with the same name and there'd be an error.
But I checked out the admin chapter and saw that we recommend adding a user called admin so it shouldn't be a problem.

I just wanted to raise this issue in case you had missed it but it seems you're on top of everything so don't mind me :)
