 * LogstashFormatter squashes the base message array and the context and extras subarrays into one.

 * This class modifies the standard LogstashFormatter to rename such fields and flag the message.
 * Also changes exception JSON-ification which is done poorly by the standard class.

 * Compatible with Monolog 1.x only.
