Add island outline and scenario buildings

❗ The software is in an early stage

• Older savegames may not work or show unexpected behaviour.
• Anno Designer does not allow to open multiple instances. After you opened it, close it before making any modifications in the savegame visualizer. Otherwise the software may hang or fail to update the preview.
• Some icons are missing in the final layout (from latest DLCs and scenarios)
• The reserved harbour space of dockland modules points into the wrong direction
• Niter production in scenario 2 is not correctly positioned
