Ability to add stuff to entities.json / possibility to dynamically load entities.json

[unreal4me]

A nice feature request to use this on a minecraft server would be to add, for example, players and display them dynamically on the map. One could take the data with RCON or any other means and append it to entities.json say: "players" : [ {"x":656,"y":97,"z":473,"name":"PlayerOne","icon":"some_head_icon", "public": "should_display_or_not?"} ] And in MinedMap.js you could go for something as simple as a setTimeout or a worker that fetches and postMessages back the playerinfo.
