Upgrade from QT4 to QT5

[penx]

To use the latest native OS features in the VirtualBox front end, QT5 is needed.

Some documentation on transitioning here:  http://qt-project.org/wiki/Transition_from_Qt_4.x_to_Qt5

e.g. this is blocking https://www.virtualbox.org/ticket/8437

This seems like a good idea. The UI is looking a bit tired on some newer OS releases.

Just to confirm: Yes, we will switch to Qt5 sooner or later.

So, is this all done by 5.1 now?

There might be still some edge cases which need to be fixed but the major work is done.

I use Arch Linux with Plasma 5.7.1 and Qt 5.7.0. After upgrading Virtualbox to 5.1.0 toolbar in my Windows 7 guest became either unresponsive at all or realy slow to response in any action. Also Windows cursor looks like black and white.
