Merge branch 'master' into language_selector

* master:

  Use i18next library locally for translations
  Use supervisor in development
  Route to set locale
  Use reference implementation for handlebars helpers (executes translation in correct context)
  Move locales to public dir for easy serving to client
  Don't load unnecessary views on every page
  Use i18n-node for server-side translation
  Node debugging setup
Dashboard title translated

locale is in use
Make URLS betterer
Localise dashboard
Localise menu

Stop grunt deleting locale files
Make i18next work
Node should watch for JSON changes in development (locale files)
Localise indicators page
Add SectionCollection::reorderByCid function
Make section navigation view a nested view
Make report view use listenTo binding syntax
