[PD] Creating signal patches by messages

I suppose the computation graph for the DSP is not updated correctly 
when creating a new box which contains DSP, but when you load (open) a 
DSP patch into a running application is done correctly.  So there is no 
reson that it needs to behave like this, its a very anoying problem as 
Im depending on dynamic creation in a running application. I can not 
simply fix the problem by turning DSP off and on again to get the 
computation graph right.
