helped with double star display

Helped Chris on the SkyTools Yahoo!Group. He was wondering about ways to make double stars more visible in the on-screen charts. He tried various display settings, including the stroke through the double, like traditional atlases. Greg replied with some tips for the display appearance. He also mentioned the double star labels. I added that the "c" key could be used to toggle the "companion" labels on and off. He liked the suggestions.
