Plasma 5.6 video

[Lucas S]

Hi

Plasma 5.6 video RC ;)

https://youtu.be/hhNNe6i9I9o

If there will be no major issues this is going to be the final Plasma 5.6 video.

Changes:
1. Revamped the end of the video
2. Included most of the suggestions from from Martin Klapetek
3. Corrected  the widget explorer part.
4. A couple of other small fixes

I can still adjust a few things if there will be such a need, so
comments welcome.

Cheers
