Subject: Implementing the templateCache in organisations list

The render() function at the moment requires a templateData struct to be
passed to it, but prior to this commit, that struct only had an
Operations field in it. We have now added an Organisations field too -
the thinking being that we only add the data we need for the page in
question and the other fields remain as nil values.

As of this commit - the slice of Organisations passed is not rendered
correctly by the template - just a raw data dump to prove it works.
