Constraints instead of clean(), full_clean() #22
Description
What do you think about moving all the logic from custom clean() methods on the model to the db constraints?

Yes, some logic is not representable as a constraint, it could be an exception which could still reside inside the clean() method. But otherwise, constraints are always enforced, there's no need to remember to call full_clean() method. Also, there are usually faster than python validation.
