  Addresses issue 2802: 'n' formatting for integers.

  Adds 'n' as a format specifier for integers, to mirror the same
  specifier which is already available for floats.  'n' is the same as
  'd', but inserts the current locale-specific thousands grouping.

  I added this as a stringlib function, but it's only used by str type,
  not unicode.  This is because of an implementation detail in
  unicode.format(), which does its own str->unicode conversion.  But the
  unicode version will be needed in 3.0, and it may be needed by other
  code eventually in 2.6 (maybe decimal?), so I left it as a stringlib
  implementation.  As long as the unicode version isn't instantiated,
  there's no overhead for this.
