Bootstrap dashboard

@jvatic This is almost working, but I'm getting mixed content warnings. Please try it out locally and see how far you get. Also, please merge jvatic/static-sprockets#1.

@lmars Please review this when you have a minute.
I think this warrants a `main` function (see [here](https://google-styleguide.googlecode.com/svn/trunk/shell.xml?showone=main#main))
