Implement formats detection (or at least enable JSON format) so that template designers may use javascript frameworks (e.g. Angular) to pull and render content.

All of the core content GET methods in contentbox-ui/handlers should allow for JSON return.

Example:

{{
/blog/category/coldbox - core handler rendering with layout
/blog/category/coldbox.json - renders JSON of category entries, according to the defined specs
/blog/category/coldbox.html - renders with noLayout()
}}
