Add checkboxes to SMMac contour screen for add labels and use auto colors.

In the 2022 release of SBMax in the contour editor we should add 2 check boxes, One that says Label all contours and another that says use auto colors. If the check all labels button is marked then the label settings that are in the contour attributes is used and labels made. The user can change these settings and still use the check box. The other box would be to use auto colors that are used in the color settings of SBmax once the auto colors is moved out of the contour editor.

When contour ability is added to MBMax this should also be done in there as well.
