The EventIcon does emit the 'activated' signal when clicked
and uses the CursorInvoker to invoke a palette the same
way as the CanvasIcon did.
We keep the same API as with the CanvasIcon, only the 'size'
property is changed to be called 'pixel_size' in order to
make clearer which values it expects to be passed. We don't
expect a GtkIconSize to be passed here.
Another option would have been to put a SugarIcon inside a
a GtkEventBox and make the properties available through an
icon property but the API would have not been as nice and
logically it seems to make more sense to have the IconBuffer
being the base for both the SugarIcon and the SugarEventIcon.
This patch has ben developed based on the one that is
proposed for the toolkit-gtk2.
