Planet SoC

Got a game going last night: A couple of bugs cropped up.

Some feedback:

• It seems that in the windows version of tpclient-pywx. If someone moves the mouse towards the star map the main window will come into focus. This issue came up when one of the players was trying to see the designs.
• Some problems with the cache. The universe is downloaded but the star map and the system tree still contain the same information.
  I think it might be an issue mostly with caching.
• I believe I need to fix my reparenting as some issues are occurring when dealing with overlords and drones.
• On windows tpclient-pywx, the starmap completely disappeared after deleting a cache to update the map. Map reappeared on the next turn.
• At one point: One of the players got a Network Error 38. Fixed by deleting cache.
