count_in/out_serializers will now count the number of specializations if a type is specialized, otherwise it will count the number of non-specialized serialization functions. as a result of this, is_output/input_serializable now works as you would expect from the name and will return true for correctly configured specialized types too. this caused some logic changes to need to happen in cereal.hpp, mostly within the PROCESS_IF macro. added some tests related to this change and #180 fixes #180
