Will pull changes where applicable manually, as inpractice2 changed so much

@davetaz have these changes been merged?

This module was not used during the training. In order to reduce confusion I am going to remove this module from the publicly visible Tanzanian deployment, thus taking it offline and not requiring merge or review.

We can then review the use of this module, merge Jeni's changes later and put it live at a later date.
