* Patrol boats and air units now highlight unit range into unknown.
* Added diagonal white lines to help guide exploring zeppelins and patrol boats (let me know if you don't like

* Changed version warning so it only warns if client is older than server. There should not be a warning if client
is newer than server. (Note this change prompted a new full download of the client.)
* Changed Splash Image
