Send observations of surroundings in the example game

[nmatter1]

Observations of surroundings should be sent to the server (state of nearby objects and the nearby agents) whenever

• Another agent is within a predefined radius
• Every 5 minutes when auto update is set to true (Automatically start updates every 5 minutes #17)
• Whenever the update state button is clicked

For now, it's fine to have the observations just be the states of the objects and the activities of other agents (the latter would probably help fix issues with multiple agents). smallville#addObservation should work for this requirement
