Renamed the eara simulations folder
Deleted obsolete run.sh and replaced it with a symlink to the basic run.sh
Updated the eara network ned
Moved much of the general stuff of the NetworkNode into its own base class

This will help us to use the same things in EARA
All traffic pattern files are now only symlinks to the simulation root
Fixed the EnergyAwareNetworkNode.ned
Fixed eara/omnetpp.ini
Fixed possible memory leak in EARA omnet version
The payload is now stored into the packets in OMNeT++

This is important for EARA which does transport the energy values
for the energy dissemination packets in the payload
Fixed segfault in OMNeT++ EARA implementation
Started to merge ARA and EARA (not compiling)
Fixes compilation errors
The packets which are dropped because there is no energy left are now recorded
Merge branch 'eara' into develop

Fixes #65
I have tested EARA by running short simulations and checked they did not crash or give
any unexpected results. We still need to check if the EARA algorithm does indeed work
by using longer simulations and adjusting the nodes battery.
