Add v1.0 support for openstack swift storage

This provides initial support for v1.0 auth in Openstack Swift.  Here is what a config block needs to look like:

        var storage = pkgcloud.storage.createClient({
            provider: 'openstack',
            username: 'test:tester',
            password: '123456789',
            authUrl:  'http://localhost:8080',
            version: 1,
            useServiceCatalog: false
        });

The version:1 and useServiceCatalog: false being the key additions.  I am sure that the integrated code could be brought more in line with the coding standards for Pkgcloud.  I put variables where I thought they needed to be, but there may be better places.
