    Check for and run intltoolize in autogen.sh
    
    On some platforms, including Heroku, the intltool macros cannot
    be found during build, possibly because the version of autoreconf
    does not respect ACLOCAL_PATH. Using intltoolize also allows
    to avoid a dependency on intltool when installing from tarball.
