[messages] [Technical Support & Bugs] opacity with line of sight, and inverted units

It's a bug in the module, not Vassal.

The Command to Hide a unit from the other player (Flip Ctrl P) has been
incorrectly implemented as a Layer instead of a Mask. 

Using a layer to hide a unit does not hide it at all, there is nothing
to stop the other player from just flipping it over, therefore it is not
really hidden at all. The transparency option of the LOS mask is making
every layer transparent including the top layer.

When the hide option is correctly implemented using a Mask trait, the
other players don't have access to flip the counter over and look at it
and the LOS transparency option correctly hides the lower layers and you
only see the transparent top layer.
