[vdr] VDR 1.4.0 - the final countdown

There have been three last minute fixes since version 1.3.49, which I'm attaching as a 'diff' to this message:

- Fixed handling the "Power" key in case a recording is going on and no plugin is active (thanks to Udo Richter; bug reported by Dominique Simon). - Fixed a memory leak in handling external EPG data (thanks to Tobias Grimm). - Fixed a memory leak in closing the video file during replay (thanks to Tobias Grimm).

Maybe some of you can find the time to apply this small patch and verify it. There have also been patches to i18n.c for updates on the Polish and Italian texts, but that's uncritical.

If nothing really serious goes wrong, I plan to release VDR 1.4.0 tomorrow afternoon.
