This adds two new C4 modules, C4::Service and ::Output::JSONStream, and makes important modifications to C4::Output. The first two are a basic framework for JSON-based AJAX services and a simple JSON output wrapper, respectively. C4::Output has been slightly refactored, with a new function, output_with_http_headers, that supports different content-types. output_html_with_http_headers still exists, and the three pages affected by this change have been refactored to support it.
