Add a configuration option for darker dialog bubbles, popups, and highlight
In ASCII, the large, solid areas of light gray in dialog boxes, the borders of popup messages, and in 'H'ighlight mode are rather hard on the eyes. This is especially true when there are large numbers of boxes/popups in quick succession, such as when you are selling multiple items at once or gambling in the casino. If possible, it would be nice to have a configuration option to use dark gray for these interface elements.
