Optimized build

Main CSS file build fixed.  Vendor scripts are no longer build via
comment annotation in index.html and use proper revving while still
being in vendor directory.
Dist directory cached

Similarly do non-dev dependencies, we want to cache built static
assets which are hosted by us.
Procfile for Heroku added

It just starts Locomotive server.
Livereload returns

We use current grunt-contrib-watch and connect-livereload for
development to easily debug on multiple devices.
