Summary

Plasma applets when they were all C++ had a way for them to signal when
they were ready for showing to the user.

The QtQuick plugin does it automatically when an applet is compiled and
the component is created with no scope for the applet to do something
async.

This is initially intended just for the desktop wallpaper, but is
generic enough for any applet/containment that does async loading on
startup.

API is chosen as we need something ref-count based to handle wallpaper
and containment both loading something asynchronous, and limited by the
fact that AppletInterface is not exported.

I wonder if that's the right API to use from QML, I guess it's fine but marking something as successful by assigning null could feel odd?

Thought about it a bit more, it should be okay.

In my case this code path is hit before any of the QML property assignments or Component.onCompletd are executed. I don't really understand why given AppletQuickItem::init() does forceCompletion()
