Title: I want to use multiple versions of a survey

* Version 0 is always the one the admin manages
* Publish a new version copies the 0 Version as the newest version
* Every version is deletable at the moment, except the version 0. Later It is just deletable if no one started it.
* Look, now I am on a horse!
