Github issue: #119

author: diane fleming
Replace jekyll-less with jekyll-assets.
Activate jekyll-assets instead of jekyll-less.
Start with a basic app.js.
Move "components" under _assets.
Move the top-level less stylesheets into _assets.
Move the component stylesheets into components/.
Master stylesheet file.
Let's move jQuery and Bootstrap assets too.
Move the rest of the stylesheets into _assets.
Some configuration settings to play with.
Include assets in the default layout.
Whoops, that's shouldn't be at the top level.
Use uglifier and yui as compressors.
Use main.less instead of app.css.
Ignore cached Jekyll assets.
Include an explicit dependency on less.
yui-compressor needs Java, too.

The Jenkins role will pick this up in production, but nothing else will install it in development.
