fix #83,support fake iconitem and container

--there are plasma widgets that break the Latte
experience concerning the parabolic effect. We fix
this by providing above them our own Latte solution
and by hiding the applets appearance. At the same
time we make sure that a folder widget is not increasing
its size above 96px. for which its appearance goes to
FullRepresentation
