Add link for linux binaries to the packages from the openSUSE build system

Project URL : https://build.opensuse.org/package/show/home:p_conrad:coins/namecoin
Built packages : http://software.opensuse.org/download.html?project=home%3Ap_conrad%3Acoins&package=namecoin

I have created an account (khalahan) on openSUSE, asked access to PMC (p_conrad) and now have an admin access on the openSUSE project (the same you are able to do, padawan).

Source packages can be added manually or automatically from github releases/tags.
Once a source file is uploaded/url added, packages are rebuilt automatically.
