Convert from ember-cli to gulp

Still some broken styles and controller methods that need to be wired up
correctly, but it is mostly functional. Gulp completes in about 800ms on
windows.
Use correct version of less styles
Enable livereload. Revert to # links until server can handle GET requests to route endpoints
Support history locations with express. LiveReload is working well now
Fixed conceptual problem with model. Introduced Response and Objection objects. Still buggy.
Only start livereload server when in watch mode
Basic angular build process
Main page displays debates. Working on navigation to statements page
More progress on angular conversion.
Fix link to debate statements
Refactor directives to use scope. Model objects are supplied via the 'model' property
Added 'new' templates. Introduced nested states, and changed hrefs to ui-srefs.
Attempting recursive directive. Not working yet, but it feels close.
Got chain working. Introduced fixture data
Inline statement-chain directive
Renamed controllers folder to routes
Make debates route consistent with others
Got score indicators working
Refactored score indicators to a score-indicator directive
Active states
