* Use Nepomuk for getting the meta data instead of KFileMetaInfo.
* Use a QScrollArea widget to embedd the meta data, as Nepomuk provides so much meta information that it might not fit into the panel.

Open issues:
* Add the possibility to configure which kind of meta information should be shown.
* Check whether the receiving of the meta data for one file also might block the UI like when using KFileMetaInfo in combination with strigi.
