npm install doesn't do bower install

[stuartpb]

Running the setup instructions in the README results in the app not having any of its static dependencies. bower install needs to be added as a prepublish script in package.json (with some inane command-line option iirc so it doesn't freeze asking if you want to do analytics).

Try bower install --config.interactive=false && grunt build

alternately you could just vendor all this stuff into the source the way Bower apparently expects everybody to do
