[!298] Make file readers return ToUniquePtr instead of a C pointer

Merge branch 'feature/grid-readers-return-to_unique_ptr' into 'master' At the 2017 developer meeting in Heidelberg it was decided that file reading methods should return a std::unique\_ptr of the resulting grid, rather than a C pointer. The reason is that a std::unique\_ptr makes it clear that the caller receives the ownership of the new object. Simply changing the return types of the relevant methods is not an option, as it will break a lot of user code. Instead the class ToUniquePtr was introduced in dune-common. It is a costum pointer class that casts into C-style pointers, std::shared\_ptr, and std::unique\_ptr. Casting to a C-style pointer will result in a deprecation warning. Using this class for at least one release will allow a much smoother transition. See merge request !298
