Adding book titles to content urls

I've added the book title to the end of the url, after the content id and version, but before the page number. I created a function in node.coffee that splits and joins the words in the title by an underscore and limits the characters to 30. Created a Handlebars.js helper that calls the split and joins function that returns the correctly formatted url in the results page.
The `getVersionedId` method should be returning just that, the ID of the content with its version appended.  Since this method is used in a number of places in webview, and not just for displaying the URL, appending the pageTitle here is not desirable.
