Configurably attach icons as payload to notification packages. By
design and due to restrictions on mobile devices *only* png is sent.
As KIconLoader preferably returns svg icons from iconPath() we fall
back to loading from "hicolor" using KIconTheme directly. Otherwise
*many* icons are dropped because of svg format.
This also improves slightly the test-case to use a tweaked TestDevice
to allow for inspecting sent NetworkPackage-s.

There are still some code paths where it doesn't get destroyed though,
like when the device gets unreachable (and the download socket doesn't
close for some reason).
Straight forward port from QJson to the native Json support.
As a note I have added 2 helper functions that make the code bit more
readable (object2qvariant and qvariatn2qobject).
Ported using KDELibs4Support, for a smaller delta, so we can keep
developing on master until we decide not to.
At the moment, it builds and installs but tests don't pass because
of a QCA2 initialization problem I didn't manage to debug yet.
