Distribute the start tag within the federation

[erlingrj]

This PR addresses #79 with following changes:

• Introduce a protobuf message hierarchy with TaggedMessage and various Signals (StartTagSignal being one of them)
• Assumes a very simple setup where one federate must be chosen as the leader and only it will send out start tags to others. This will of course not work if several federates think they are the leader
• Any federate that is not the leader will block indefintely waiting for receiving the start_time
• When start_time is received for this first time by a federate it will be forwarded on all other connections.
