libpng3 upgrade will remove kde development packages

[Josh Metzler <joshdeb@metzlers.org>]

The new libpng3 (1.2.5.0-1) renames libpng12-0-dev to libpng12-dev, which 
seems to be intentional on the part of the new maintainer.  I have a number 
of kde development packages which depend on libpng12-0-dev, though, and so 
will be removed if I upgrade libpng3.
