Update to 0.31.  While here, make this package also install the xml-i18n-tools
utility to obsolete the standalone xml-i18n-tools package.

Changes since 0.30:
* Usage of [no-xml] option in AC_PROG_INTLTOOL to avoid requiring
  XML::Parser Perl module. (Rodney Dawes)
* Support for C#. (Rodney)
* Support for running intltool-update without autoconf, or with
  po/Makevars file (as used in gettext). (Danilo Segan)
* New XML merging (compatible with pre-0.27.2 intltool) -- bug
  #130802 -- entity decoding and encoding is not done anymore for
  XML. (Danilo)
* Multiple-output XML merging now produces simpler files, and sets
  "xml:lang" only when translation is used -- bug #46650. (Danilo)
* Support for passing comments to translators from XML and GConf
  schema files. (Danilo)
* Many bug fixes (Rodney, Danilo, Callum McKenzie)
