Google Analytics update

[allejo]

While using composer for ApiGen, it's locked at 1.1.* of this theme, I was wondering if there could be a version bump with the updates from #21 or allow ApiGen to use either 1.1.* or dev-master?

This theme will get a version bump with the merge of the new style in #26. This means, then the required google-analytics code will be available.
