Update storyboard strings, qqq files when master files change

en.lproj/Main_iPhone.strings now updates automatically when
new things appear in Main_iPhone.storyboard.

qqq.lproj/*.strings files now have stub entries added for any new
entries in en.lproj/*.strings files. These should be very visible
in code review if they don't get caught before committing. :)

Extra entries from the qqq.lproj no longer in en.lproj are also removed.
