Implement minimap.

[aszlig]

Either integrate http://map.tiberium-alliances.com/ or write our own stuff.
I'd personally prefer to have a map based on the current live version rather than a periodically updated map.
Maybe its possible to work this out together with @limitium in order to either to live stream data to his map server or to use our own implementation.

For our own implementation I'd probably go with XMPP and use pubsub or personal storage for this, but let's see which works best.
The important part about the data gathering is to keep traffic minimal, so we need to write a compression algorithm.
