Enabled the battery vector for all simulations
The OMNeTBattery has a new parameter energyVectorDelta

This controls how often the residual energy values are saved in the cOutVector
Added default value for the OMNeTBattery.ned parameter energyVectorDelta

The default will write the residual energy to disk when it has changed by
0.5 percent since the last write. This will create at most 200 entries per
node which should not be too much
Merge branch 'master' into eara
Implemented the basic EARAPacket which can hold energy information
Fixed indentation in PacketFactory (no logic has changed)
Created the EARAPacketFactory which is responsible for creating EARAPackets
Implemented the EARAPacketFactory also for OMNeT++
