commit 082d0a19fd6d17a1fa157e915220fe4dbc960ce2
Author: Pedro Castro <mail pedrocastro org>
Date: Sun Apr 10 22:25:49 2011 +0100
Added initial support for automatic translation, based on a patch from David Krkoska (bug #595084). Currently only 1 subtitle can be translated at a time, and Google Translation is used.
