REVISION SUMMARY
  The old code was connecting the KIconLoader signal to implicitWidth/HeightChanged but never actually set a new implicit size.
  Also, while at it use "setImplicitSize" - it's also marke internal but public like setSize and uses qreal instead of QSizeF.

TEST PLAN
  Comes with a unit test
  
  Also ran the following in qml scene and changed settings, the icon item would adjust itself:
  
    import QtQuick 2.2
    import org.kde.plasma.core 2.0 as PlasmaCore
    
    Item {
        width: 500
        height: 500
    
        PlasmaCore.IconItem {
            source: "user-home"
        }
    }
  
  I wonder if we shouldn't scale the implicit size with Units
