Gwenview fails to compile with Qt5 libkipi

[Christoph Feck]

Hi,

trying to compile today's gwenview/master with libkipi/master, I got 
this error. I don't know if it's planned to release the Qt5 version of 
libkipi with KDE Applications 15.12, but if it is, we need to have a 
working and stable API.
