KStars FITS Viewer tool is now working. It features a simpler interface, and uses the powerfull CFITSIO which made life easier as well. I removed the brightness/contrast tool since it was pretty slow and it can be accomplished using the histgoram at any rate, which is much more powerful than any bri/con controls.

This pretty much sums the last _major_ porting effort to KDE4 for the tools I've maintained. Looking forward to improving the codebase now.
