    Add hight contrast option in Modedit. In hight contrast mode, solder masks and solder paste are shown.
    this option was possible only by modifying the way display options are managed.
    before these changes, display options were a global DISPLAY_OPTIONS class instance.
    Now each EDA_DRAW_FRAME(and derivated classes)  includes its own DISPLAY_OPTIONS class instance.
    As a consequence, some duplicate display option variables in these classes have been removed, because there were just duplicate variables of the  DISPLAY_OPTIONS class instance.
