Right now, every QML plasmoid can provide a number of properties
(6, actually) to specify some size hints (maximum, minimum and
preferred).
If you don't provide those properties you get many warnings because
of the missing changed connections. This patch removes such warnings
by making sure the property is present before connecting and querying
the property at all.

This adds the necessary bits, actions handling, showing / hiding of
toolbox and a hooks for config interface and add widgets.
The interesting bits:
Toolbox separate on the scene
For declarative containments, we add a declarativewidget on top of the
view which loads the "org.kde.toolbox" package. The toolbox can differ
per platform, layout of toolbox and containment can not "leak" into each
other.
ToolBox import
The most important and interesting bit is the list of actions the
ToolBox exposes, it's collected from corona, containment. The latter is
actually problematic, since we don't get access to the actions
internally provided by Containment
(ContainmentPrivate::addDefaultActions).
Containment::setToolBox(AbstractToolBox) being protected, we cannot
register our declarative ToolBoxProxy implementation to the containment,
so we have to wire up settings and addwidgets separately. Sorting of the
actions is "random", and expected to be done by the QML toolbox
implementation, based on objectName strings.
REVIEW:107232
setElementPrefix does not trigger repaintNeeded() from the svg object;
repaintNeeded() is for internal changes. if you change the svg from your
own application code, the app code needs to react to those changes in its
own time and way.
so margins was never seeing that it was getting changed when setElementPrefix
was called -> pixel imperfections in layouts.
