    Rename locale tags to comply with rfc5646
    
    - From rfc5646 (section 2.1): A language tag is composed from a sequence
      of one or more "subtags", each of which refines or narrows the range
      of language identified by the overall tag.  Subtags, in turn, are a
      sequence of alphanumeric characters (letters and digits),
      distinguished and separated from other subtags in a tag by a hyphen
      ("-", [Unicode] U+002D).
    
    - Update Makefile to fix <html lang=""> definition in locale-specific
      html files.  Previously, locale-specific files were all produced with
      lang="en", even though the content of the file was not in that
      language. This update changes the Makefile to set the language value
      that corresponds the locale-specific html file.
