Translators: Updated translations in Transifex

[Felix Schwarz]

I updated the translation files for MediaCore [1] and there are many new
strings to translate</a>. Everyone is welcome to participate here.

Please note that the strings are not final yet so there will be changes and
maybe some extra work if you start now. However I'll merge your translation
updates regularly to keep the losses as small as possible.

If you update your MediaCore translation locally, this is a good time to
contribute to MediaCore! Just go to Transifex and update the messages.

Cheers,
Felix
