Made favourite stars more visible.

I couldn't really see the previous favourite stars on some shows with dark banners so this is a suggestion. I've only tried this on my Galaxy SII which uses drawable-hdpi, so I don't know if the m- and xhdpis look good.

I'm not so sure about this one. I think the yellow is a bit ugly. Perhaps a more pale shade would look better?

I just grabbed the yellowish equivalent of the blue you used for the progress bar from the Android style guide. If you want to pick a color, either from there or anywhere, I'll recolor the stars, or should I just try something out?
