Nexus spec modification

Hello,

please add to the spec file of nexus for the future releases to create a symlink (first removing previous) to have nexus-professional-latest poiting to the current veruion (e.g. now is nexus-professional-2.5.0-04 , which i am going to create manually ):

rm -f nexus-professional-latest; ln -s nexus-professional-$version nexus-professional-latest

so we will not have to change version in puppet. And then we will reference everything to this nexus-professional-latest.

Thank you.
