Cantor master is now Qt5/KF5 based

[Filipe Saraiva]

Hello community;

Cantor master branch is now Qt5/KF5 based! Thanks for all the team
involved in this work!

The port work is finished for Applications 15.04. Next step is to drop
kdelibs4support for future releases.

This release will include a new backend for Python 3 too, developed by
Minh Ngo during SoK 2014.

Thanks again and best regards;
