Fix and accelerate generated __hash__ methods (#296) * Fix and accelerate generated __hash__ methods We now create a method like we do for __init__ and hash also the class of the instance. * Add/fix news fragments * Hash random numbers instead of the actual class * Even simpler: let's hash the unique filename Or rather it's hash, because hashing ints is very fast.

Generated ``__hash__`` methods now hash the class type along with the attribute values.
Until now the hashes of two classes with the same values were identical which was a bug.
The generated method is also *much* faster now.
