  add locks around gettext calls

This should fix #2013. I am unsure whether this seriously infulences the performance since mutexes are somehow slow, If this implacts the performance we could also change it in a way that the mutex is only used when we have actually 2 active theads (the loadingscreen) (replace `std::lock_guard<std::mutex> lock(get_mutex());` with something like 
`std::unique_ptr<std::lock_guard<std::mutex>> lock(is_in_locaingscreen? new std::lock_guard<std::mutex>(get_mutex()) : nullptr))`
