MANET support

Beta version of gossip support in MANET + OMNET++ integration (and demo)
Main changes in core:
- extended scheduler for non-periodic time-triggered tasks (PeriodicTrigger(period) -> TimeTrigger(period, offstet))
- added network layer (...deeco.network package) responsible for packaging local knowledge as network messages and packets, reassembling packet into knowledge, gossip-based rebroadcasting of received belief

Simulation/integration project is Java / C++ parts of OMNET++ integration
- full support of MANET-based communication, partial support of IP

simulation.demo - tests and analyzes the outcome of gossiping in manets based on a simple firefighting case study
- contains scripts for automated generation of scenarios and log analysis
