[TYPO3-mvc] Validation in TCA and extbase

We need to work on the error messages! Could you please create a ticket?

:-(

Actually the Validations in @validate and the Validations in TCA have
nothing to do with each other.
All @validate-annotations are parsed in Extbase and can currently be
found in Classes/Validation/Validator/*.

Currently, one manually has to make sure they fit together (Validations
in TCA and annotations).

I doubt that we can still change this before 4.3, as I suppose it would
involve quite some changes and refactorings.

Besides that, I don't really like that one has to care about
synchronizing these validators, but I don't have a nice clean solution
to this problem right now.
