Correction of 2 links that refered to allgo.inria.fr.

Correction of 2 links that refered to allgo.inria.fr. I changed them to allgo18.inria.fr. Note I do not alter api.rst links as it is already done in branch sletort. I also not alter samusa link, even if it refers to the old version, as no version of samusa is available in the new site.
