Refactor website-ui

[maxkfranz]

• Add a build system using webpack and npm scripts, using slush-js: https://github.com/maxkfranz/slush-js
• Port the LESS stylesheets to standard CSS that uses PostCSS
• Refactor the source to use import across the files. It will be necessary to wrap the Angular dependency system in the app's boot phase in order to make this possible.
• Replace the in-repo dependencies with dependencies in package.json
• Replace Angular with React. The source isn't too coupled with Angular. Mostly the templates would have to change. Using JSX may make this process easier at first. Then there's probably a JSX-to-hyperscript converter we could use for the next step.
• Upgrade Cytoscape.js.
• Replace Qtip with cytoscape-popper and Tippy.js
• Remove the jQuery dependency
• Remove the Fastclick depdency
• Remove the localForage dependency
• Replace PubSub.js with EventEmitter3
• Replace jquery.autosize with autosize
