re-enabling play-autosource slick

The code was already ready for the new action builder. I don't know why it was not compiling for you.
It's possible that the problem is related with dependencies on play-slick plugin. Let me know if that's the case.

As said before, the dao is being moved to a separated project and ported to slick2.0. Next step is to integrate it with play-autosource.
