 * Improved the instructions.
 * Disable attack button with no soldiers.
+* Added credentials to attack status requests (others can't spoof to see who you're attacking anymore - my bad!)
+* Began work on spying infrastructure.
+* Made the attack button more generic - can reuse a lot of attack code for spying code.
 * More coming later today...
