Remove this bundle key from the generic Info.plist files as it's not
really useful there because none of our samples except "internat" is
localized.
So just add a special Info.plist for this sample and add values
corresponding to all the languages for which we have translations to its
CFBundleLocalizations.
Also update inc_year script to update them automatically the next time,
to prevent them from becoming 3 (for one, or 13 for the other one) years
out of date again.
Don't use CFBundleSignature, it was only needed for Classic Mac OS
compatibility. Similarly, LSRequiresCarbon was used to distinguish the
"new" Carbon applications from the Classic ones and is not needed any
longer.
CSResourcesFileMapped might still be used, but it's just an optimization
and we don't need it and it's just a s gratuitous difference with the
template used by Xcode, so remove it too.
Just put the keys in the same order as the one used in Xcode template
and samples/minimal/Info_cocoa.plist based on it (which is almost
alphabetical order, except for LSMinimumSystemVersion which comes after
NSPrincipalClass at the very end for whatever reason).
No real changes.
