- Fix http://trac.edgewall.org/ticket/9439, http://trac.edgewall.org/wiki/TracL10N

- Bump PORTREVISION

Current Trac port requires no Babel (devel/py-babel), but it behaves
differently when Babel is present and when it is not present in the
system. Most notably, when one installs Trac 0.12 without installed
Babel and installs Babel later, Trac will refuse to work with the error
"KeyError: trac/locale".
