Merge branch 'develop'

The ARA Algorithm does now support basic path finding. There is no route maintenance, failure handling or pheromone evaporation.
The OMNeT++ simulation does also work
replaced CHECK_EQUAL with BYTE_EQUAL in unit tests for routing table (conversion errors from size_type to string type)
added a test stub for class OMNeTStochasticForwardingPolicy
added parameter support (by means of NED files) in class OMNeTARAClient
added two parameters to the OMNeTARAClient NED file (RandomNetwork.ned) and added parameter support to the corresponding class
a runtime exception is now thrown if the forwarding policy is unknown
Merge branch 'policies' into develop
Updated the UMl diagrams to the current state of the source code
added license script for license templates
Made git ignore all .tkenvrc files
Added the first INET/MANET test network
Added the INET/MANET framework as submodule
Added the symlinks in include/inetmanet to gitignore (they are automatically created via make)
Source code can now be built and linked together with the inetmanet code
Fixed small bug in the TrafficGenerator
Added built settings to eclipse / OMNeT++ IDE settings
Ara-Sim does now actually compile and run together with INET/MANET
Added eclipse/OMNeT++ local settings to gitignore
The ARATrafficGenerator does now basically work
Removed old test network: Line.ned
