The PacketFactory can now ordinary DATA packets
Removed the createOMNeTPacket method from the omnet packet factory

This simplifies the class a little bit more and removes issues with
using the class from the outside
Some of the basic functionality has been transferred into the new AbstractNetworkClient
Completely removed the MessageDispatcher class

The functionality is now completely implemented in
AbstractOMNeTARAClient
The allTests Makefile target does now create the ara-sim binary
Minor cleanup in ARA::omnetpp::ARA
The traffic has now its own ControlInfo class.

This will be necessary soon to measure the packet delay
The creation time for each Traffic packet is now recorded in its control info.

However, this information is not read yet
Added a new Makefile target cleandep
Minor cleanup in the routing table data persistor
Merge branch 'delay' into develop
