[aur-general] Merge python-scientific in python2-scientific

[Hector Martinez-Seara]

Hi,
Please merge python-scientific
https://aur.archlinux.org/packages.php?ID=30945

in python2-scientific
https://aur.archlinux.org/packages.php?ID=51615

both make reference to the same package but the first do not compile,
is out of date, the name is wrong as is python2 dependent and it is
orfan. I'm the maintainer of  python2-scientific. Right now It is only
used as a dependence of mmtk which I'm also the maintainer.
