lxqt to 0.10 from 0.9

[paxmark1]

I received the newest milestone for lxqt earlier here on sparky and testing than via siduction.  I performed a dist-upgrade and for me, no major problems noted.  I did read up on debian bug 792321 and chose to go ahead anyway.  For me it is a fresh install of libkf5screen6.  The lxqt updated  versions are 0.10.0-1 from 0.9-6

Things could still go wrong for others on different architectures.  This was done on an atom 386 netbook without  kde5-plama5  I use sddm on this machine instead of lighdm. 

There is a steady progression of adopting tier 1 kf5 components

This release, we focused on cleanup, polishing and quality-of-life
improvements, with over 400 issues fixed and dozens of new
translations. We have also gained two new frameworks: Solid, which
replaces liblxqt-mount and some custom power management code and
libkscreen, which replaces system xrandr calls and is wayland
forward-compatible.
