Since this menu item is inserted automatically by the OS, we don't need
to localise it at the application level.

I get the sense that the word order, particularly for the "Help" menu
item, may be different in other languages. Rather than force a certain
word order by concatenating strings, include the application name in the
localisation by making it a format string with an argument.

Don't think concatenating is the right approach here, but good enough
for now.

Copy strings from AppleGlot dictionaries to test that our localisation
works properly.

Still some concatenated menu items that need translation.

I miscopied this title when I was looking at a template MainMenu.xib in
Xcode.

While I was trying to make a test translation strings file using the
AppleGlot dictionaries, I discovered the mistake.

To support more languages.

Also, this document says that Base.lproj is for nib files and a quick
skim seems to indicate that translation files should live in a folder
named after the language code they use.
