Bug#692410: license information for Math::Libm

thanks a lot for digging that up! I think that the email documented at
the github URL is fully sufficient. I'll include it in d/copyright and
upload Math::Libm shortly.

Regarding the other Slic3r dependencies, I seem to remember
libmath-geometry-voronoi-perl had a reply from upstream and should be
ready for upload as well; but could you remind me if there are even more
dependencies that I've forgotten?

Florian
