Fixture: add non const Setup() and TearDown(). (#285)

* Fixture: add non const Setup() and TearDown(). This allows write-access to the State variable, which is important in upcoming user-defined counter functionality. * Fix const placement in the Fixture methods. * Fixture: use const_cast instead of static_cast.
