Add missing fields for tournaments

[istar410]

Add missing fields like team password (#88), player/manager pseudo and max number of teams in a tournament (#49). Also fixing unique registration per event validation.

I would really appreciate some help for fixing tests :)

I'm not sure that the validator checking if a manager is not also a player is correct. The last failing test is about if we should raise IntegrityError or ValidityError.

Hi, so, I finally managed to focus enough to run the tests and investigate what's wrong, here's what I found out

I'm not sure that the validator checking if a manager is not also a player is correct. The last failing test is about if we should raise IntegrityError or ValidityError.

Yes and no. Yes: the validation test is completely broken at the moment. No: it's not a matter of validation error or not; test code is raising errors on the first instance of registration, where no conflict should exist yet. Something is wrong with validation in a way that I haven't pinned down yet but which is definitely exhibited by our tests.

As for the second kind of tests, they happen to crash because test code was pushed in the pull request, and user tests previously written by @Lugrim check for the presence of the email validation URL in the body of emails returned by calling the registration URL.

So we have two things to do before we can merge this PR:

• Write an actual body in the content of the email and change the tests to check for that instead
• Fix the registration conflict validation

(oh of course we will have to rebase this whole mess with dev before merging)
