![Travis Build Status](https://secure.travis-ci.org/bschussek/symfony.png?branch=remove-form-validators)

This cleanup has been lying on a disk for a while, so here it goes.

The FormValidatorInterface has been removed in order to reduce the complexity of the Form API. The same expressivity can be achieved by using POST_BIND event listeners. The POST_VALIDATE event introduced in e6577debf6892afeb2d10eb8a3a0fae0d55c9545 can be replaced by a POST_BIND listener with low priority.
