Review request for kdelibs.


Changes
-------

Updated to account for Aaron's suggestions (thanks for the tip on signal/slot connections, I might use it elsewhere in oxygen); and committed 


Summary
-------

As discussed with Aaron, changed QTimeLine into QPropertyAnimation. This should provide smoother and more efficient fade-in/fade-out effect.

This is the first of two patches.
The second will use different pixmaps on mouse hover, but might also require change to klineedit.cpp
