npm cannot handle "main" as an array - must be a string

There's currently no way to include CSS in the package.json file, so it will need to be included manually by the developer.

The current package.json does not install with npm install, so this is pretty much the only option. Documentation for npm install could include ways to include the CSS file (I include it with @import in my main.scss file and that works just fine).

I also corrected a few URL's that went 404 in package.json.
