[ndnSIM] Adding route manually

[Shahid Md. Asif Iqbal]

Dear Sryridon,
I sorted out that the problem occurs due to the add of the following code
segment in the onIncomingData() function of forwarder.cpp:

 Name dataName("/");
 dataName.append(data.getName().get(0));
 dataName.append("D");

Thanks
Asif
