DDLightarMenu: Numbered mode item refresh fix & new item number colors

DDLightarMenu: For numbered mode, implemented a fix for refreshing the menu after the user types an item number to select/highlight it. Also, added 2 new color settings to specify the color to use for writing the item numbers: itemNumColor (for non-highlighted items) and highlightedItemNumColor (for the current highlighted item).

 will be outputted, so in numbered mode, the menu's height should not go further
 than 2 lines below the console height.  Otherwise, the display of the menu will
 not be correct if the user decides not to enter a number.
+When numbered mode is enabled, you can specify the color used to display the
+item numbers.  For a non-selected item, set .colors.itemNumColor.  For selected items,
+set .colors.highlightedItemNumColor.  This is separate from the item color setting
+(.colors.itemColor).  For example:
+lbMenu.colors.itemNumColor = "\1c"; // Use cyan for the item numbers for non-selected items.
+// For the selected item, use high cyan with a blue background for the item number
+lbMenu.colors.highlightedItemNumColor = "\1" + "4\1c\1h";
 
 This menu also supports multiple options selected (by default, that is not enabled).
 To enable that, set the multiSelect property to true.  When enabled, the GetVal()
