added a new test scenario
Fixed the RoutingTableWatcher
Fixed bug that prevented the ARAClients from remebering more than one route to destination
added variable for counting the number of messages which could not delivered
Added a scruipt to start the debugger (nemiver)
Fixed failing tests
Added some more statistics recording to the omnet simulation
Fixed bug in DUPLICATE_ERROR packets (wre not processed)

Because the DUPLICATE_ERROR packets iherited the sequence number of the
packet that caused the DUPLICATE_ERROR the receiving node did never process
the DUPLICATE_ERROR because he thought of it as another duplicate.
Current stet of development (not working)
Fixed the failing tests. Only one failing test left (not implemented)
The TTL value is now correctly processed. Packets with TTL < 1 are no longer relayed.
Implemented a new pheromone initialization function.

Fixes #44
Merge branch 'TTL' into develop

Fixes #42
The maxTTL configuration parameter is now correctly read from ned
The TTL for datapackets in simulations has not been set correctly
Fixed error in loop detection.

The link has not been deleted from the routing table because the
source address and sequence number of the duplicate warning packet
matched the original data packet and was thus ignored as diplicate
itself.
The packetFactory is no longer part of the global environment

Instead every ARAClient has now its own PacketFactory.
This is a nessecarry preparation for the upcommung change, that the
packet factory will now the parameter for the maximum hop count (TTL)
which can vary between distinct clients
The packet factory does now hold the maxHopCount value itself
The message dispatcher does now use a packet factory to create the OMNeTPackets
The ARA client does now try to deliver a packet that he received twice (loop)
