Multiple jurisdictions

This isn't yet ready for merging.

This includes tidying up of the prototype folder, removing things that shouldn't be there any more, and the auto-generation of XML and Surveyor versions of questionnaires for every country. @benfoxall, there are a couple of things that I need some direction on:

  1. whether the titles in the Surveyor questionnaires need to be different for each country
  2. the additional fields in the questionnaires about which jurisdiction they cover and what state they are (alpha/beta etc)

Otherwise these should be ready for use in testing to build support for switching between jurisdictions.
