plasma: reimplement folderview applet meta information
requires:
6be64be278
TODO: KFileMetaInfoItem::toString() for special cases like dates, bitrate,
etc. like those handled in kdelibs/kio/kio/kfilemetainfo.cpp.
KFileMetaInfoItem::suffix() and KFileMetaInfoItem::prefix() are not
implemeneted but KFileMetaInfoItem::toString() will cover both
