### Build 16

  it did not have a real purpose.
- Added a help button + window function (e.g. to explain the multi player
  menu).
- Play a fanfare when a military site gets occupied and another fanfare
  when the player is under attack
- Reworked the multi player launch game menu - now different clients can
  control the same in game player together (share the kingdom) and other
  starting positions can be "shared" in as second (third, fourth, ...)

  useful)

  saturate the first marble mine.
