Things coming along, zones can be started/shutdown as needed

In 0.7.10 I'm now finishing the feature where zone servers can be automatically started and stopped as needed.  A while back I had implemented automatically starting zone servers when a player travels from one zone to the next, but it was never used because when you first log in the login server and the login client scenes still assumed the needed zone server was online.  So up until now all implemented zones have always been started and kept running.  This has limited further implementation of more zones. 

Currently there are 5 zones implemented, covering the entire British Isles region.  My development test server is an 8 core FX CPU, which can support running around 6 zones at most at the same time.  5 works better though.  So I've been maxed out in what I can test before pushing to the live server.  The live server has 16 opteron cores which each core is better performing, so it can probably support around 16 or more zones, but I don't do initial testing on that server.  The live server cluster will eventually have more servers added as well.  I'm targeting roughly 50 concurrent zones when the game goes public, maybe more. 

But these new changes are the most important step for adding new surrounding zones.  So now, when the master server starts up it automatically starts expected high traffic zones only, which are the national capitals.  Currently that is just London (zone 0).  Then as needed other zones are spun up.  When a zone is idle with no players for 30 minutes, it reports this to the master server.  If the master server is in the normal auto mode, it then tells the zone server to spin down.  Later when a player needs that zone again the master server will spin it back up. 

So after this functionality is all tested, this will allow me to expand the game to further areas.  The plan is to do northern Europe, the Mediterranean, out into the Atlantic, and down the African coast, eventually getting to India.  That will be a pretty large area and cover over half of the nations.  Then tackle east Asia and the American east coast to finish adding all nations.  After that it will just be a process of finishing the entire world map.
