automate portus release

This commit adds a "release.sh" script that will release portus in the
build service.

It assumes you will have already tagged and update the VERSION file, as
well as updated the CHANGELOG (see http://port.us.org/docs/how_we_release.html)

It includes a small fix in the make_spec.sh that checks for bundler

+release.sh automates the creation of a project in the open suse build service
+for a new release and it copies all the dependencies.
+
+To be more specific, it creates a subproject in Virtualization:containers:Portus
+and it copies all packages. Then, it will set the version in the spec file and
+get the tarball for that specific version (it assumes you have tagged git)
