----------------------------+-----------------------------------------------
 When re-opening a previously saved RuntimeMap containing Base Layers there
 is an iterator across RuntimeMapLayers that always tries to set a
 .Visible.  Unfortunately this property is designed to throw an exception
 for base layers and the internal calls need to be safer.

 I added an:

  if (this.Type != kbaseMap)

 around three instances of setting the visibility in "RuntimeMapLayer.cs"
 at/around lines 146, 722 and 764.

 There may be a better way of handling this.
