Please move some ports from CAD to science

[Nakata Maho]

Hi, Pedro

> When I did some of the ports in the CAD category there was no science section

> Nowadays we do have a science category, and furthermore we have real CAD ports
> (basicly Aster and CalculiX) that are better suited for the CAD category. I
> suggest that the following ports are moved to science:
> 
> felt
> femlab (the website for this doesn't exist anymore)
> freefem
> kaskade
> 
> I also consider metis-edf should be in the math section, near to it's cousin
> metis.

> This is all, of course, very subjective, so I won't suggest it again.
