use bay12-provided translate_name function

[ab9rf]

50.10 added a std::function hook to call translate_name, in light of #3820 we should probably figure out how to use this because it appears our code for this is possibly out of date

the value of the published global translate_name is of type std::function<void(namest*, string&, char, char)> where namest is bay12's name for what we call language_name. we can probably use this with a reinterpret_cast<std::function<std::function<void(namest*, string&, bool, bool)> >(df::global::translate_name)->(name,string,false,false) but that needs to be tested
