Setting up the angular demo client

[lloydwatkin]

Steps to complete:

• Install npm (old nodejs does bundle it) - better still use nvm and install iojs https://github.com/creationix/nvm
• Install package files npm i . in /usr/share/nginx/html
• Install grunt-cli and bower: npm i -g grunt-cli bower
• Run grunt to build source: grunt index
• Generate the index file: grunt index
• Install bower dependencies: bower install (--allow-root if this makes things easier)
• Switch root folder in nginx conf to /usr/share/nginx/html/build

Issue on bower install it doesn't know which version of angular to install (complains about conflicting values)
