This eliminates the need for a resource file at run-time.
locale/LanguageNames.txt is intended as a "source file" that is infrequently
changed as the set of supported languages changes.
The intermediate step, of appropriately copying that file into the C++ source
code in src/Languages.cpp, was done by hand.
In XCode, I set locale/LanguagesNames.txt and src/Languages.cpp to be
interpreted as Western encoding, and then the copy-paste was easy in the
editor.
The resulting C++ source code file now has string literals that are not 7-bit
ASCII.
