Storage docs show link to datastore dataset docs when they shouldn't.

[marcgel]

Wasn't sure of best solution or else would have created pull request.

This page: http://googlecloudplatform.github.io/gcloud-node/#/docs/v0.6.0/storage shows "See the Dataset documentation..." when it shouldn't.

In source: https://github.com/GoogleCloudPlatform/gcloud-node/blob/master/docs/components/docs/docs.html, line 87

    <p ng-if="!isActiveUrl('/docs/datastore/dataset')">
      See <a href="#/docs/datastore/dataset">the Dataset documentation</a> for examples of how to query the datastore, save entities, run a transaction, and others.
    </p>

should be either "isActiveUrl('/docs/{{version}}/datastore/dataset')" or maybe "isActiveDoc('datastore')"

I have a fix for this in #229 - a live example is up on my fork: https://stephenplusplus.github.io/gcloud-node/ Please leave any feedback over there.
