Changed the way Semafor is displayed.
(I don't know if anyone is using FNC_Semafor, but I will release it.)
When the direction is a square, as in xard, an arrow is displayed.
When the direction is opposite to the square, a dot is displayed.
Please refer to the attached image for more details.
Added a hide/show button for semafor.
The initial state of the button is hidden.
