Provide JSON pretty-printing #42
Description
Currently AnaLog can distinguish, format and highlight the syntax of XML documents being printed into the log. It seems a cool feature but XML doesn't get more popular these days especially when it comes to logging of inter-service communication where REST/JSON approach is the de-facto standard.
It is required to implement the same functionality (detection, formatting, pretty-printing) for the logged JSON documents as well.
Additionally, to keep the application structure clean, it makes sense to extract the above logic into a separate, manageable layer which would be implemented by XML and JSON handlers (possibly with other formats support in the future). Every layer should have a toggle switch in the settings to let the user decide if he/she wants to use in or not (say, for the sake of performance).
