Attach css and javascript assets to projects

Previously, CSS and Javascript would be deployed to a /shared/VERSION/ directory. This worked well as long as the CSS and Javascript was relatively unchanged between versions. However, this poses a problem when the HTML/CSS is changed in any major way and project versions are not in sync. This exact thing happened in the last release, as the redesign changed the CSS for Riak version 1.4 and RiakCS 1.3.1. Since the 1.3.1 release updated the shared assets, Riak 1.3.1 is now broken (using the updated shared 1.3.1 rather than the old 1.3.1 CSS).
