[Ayatana] White text in lenses doesn't work well with light background images.

[Jo-Erlend Schinstad <joerlend.schinstad@xxxxxxxxx>]

It's fantastically cool how the lenses background color changes with the
desktop wallpaper. But when the wallpaper is a light one, then the text in
the lenses become difficult to read. For example, Oneiric comes with the
«Touch the light» wallpaper. At present, on my laptop, when I'm using that
wallpaper, I'm completely unable to read any text in the dash or other 
lenses.
So the text needs to change with the wallpaper dominant color as well,
although I don't know exactly how.

The lense icons also become very anonymous with a light wallpaper, so
something needs to be done with them as well.

I also think it would be very cool if the indicators got the same background
color as the input field and the launcher entries, if they're going to be
usable while the lenses are being displayed. I don't really see the point
in that, but I suppose it doesn't do any harm.

I also think the lenses icons should be a little bit bigger. After all, 
they're
fairly important parts of the interface, and they need to be more visible.
