 All planets have the potential to change state or mode to the next one in
the list.  Years over a certain amount are broken down into smaller time
frames with a random chance of occurring.  Ie. 100 M into 1000 x 100000 with
a 1 in 1000 chance every 100000 yrs.  Game time is actually accelerated to
induce more changes to the system.
 A planet changing state or mode destroys probots/minebots, cache, and info
collected on the planet.

 In addition several other changes may take place:

  5b to 2c
  2c to 5c
  3a to 5b
