Looks like OSX changed the default format of its locale, which is not valid anymore for gettext/boost::locale. Solution based on investigations and patch by Kieun Mun (@kieuns), with some further tweaks by Ankit Meel (@ankitm), many thanks. Also add an exception catcher on `std::runtime_error` in `bl_locale_set()`, since in OSX catching the ancestor `std::exception` does not work with `boost::locale::conv::conversion_error` and the like for some reasons.
