add custom menu item to array <Value>: text=<Var/String> returnvalue=<Value>

X3:Terran Conflict
Adds a selectable option into a menu array.

Additional Notes:
  • The return variable does not have to be an integer, and could just as easily be an array or another data type
  • If a menu item has a return value of null, 0, or [FALSE], then it is not selectable
  • If the number of selectable options is not enough to fill the screen, then this argument has no effect.
  • Menus can not use the [colour][/colour] colour tags. They can however user the \033Y \033X colour tags (for all colours)
  • Menus can not use format tags
