Committing patch from Mederic Boquien.
Use alpha transparency in InfoBoxes instead of a bitmap pattern.
Also, use transparency to fade transient labels, instead of fading them to the background color.
We should probably use transparency to fade planet trails as well.
Thanks a lot for the patch, Mederic! Sorry for misspelling your name; my SVN
editor freaked out at non-ascii characters :(
