ColdFusion 11: query column types preserved when serialising to JSON, eh?

G'day:
I'm playing catch-up with the comments on the blog, and one of said comments from Roberto Marzialetti got me looking at an old article: "ColdFusion vs JSON. How to make a developer cry". In this article I mooted an alteration to how ColdFusion serialises query data so as to preserve the column types. This is critical with queries because CFML operations on this data such as QoQ is type-sensitive. So we need the data type.
