mosaic, especially) for next release.

* modules/codec/ffmpeg/video.c, modules/demux/mp4/mp4.c: backport 11229 to fix playback of some h264 streams.

* include ru in the builds again although it's far from being complete (685 translated messages, 716 fuzzy translations, 1632 untranslated messages)

* en_GB: partial update

* ALL: removed the translations to Bengali, Modern Greek, Hindi, Hungarian, Burmese, Nepali, Norwegian, Polish, Pashto, Russian, Swedish, Tetum & Tagalog from the builds, because each of them contains less than 20% of translated strings (refs #143)

fixes #211

Please do not forwardport this commit. I'll do that in a couple of days. I have other pending changes to intf.m in trunk at the moment, which are not finished yet.

    - reverted to change "VLC Einstellungen" to "VLC-Einstellungen", as this is no good style for a menu entry in my opinion
    - included all other fixes of strings that are still in use (not that many, as the diff was created from a _very_ old version of de.po)
* added various fixes to the Streaming-wizard-strings myself
