Capability to export and import JSON

[NoDiskInDriveA]

This plugin is extremely useful, however serialized PHP can be hard to read, modify and diff (both manually and automatically, for all kinds of collaboration tools), so I - currently collaborating with others on a wordpress project - felt the need for another format. I chose JSON as it is very readable, well known and comes with all current PHP versions.

My small extension of your plugin adds a JSON export option and also allows for uploading settings in json format (only if available on current PHP runtime).

I'm fairly new to the wordpress ecosystem, so I don't know:

• whether all the existence checks for the "json_*" functions (>= PHP 5.2.0) are required or useful
• whether a feature supported by serialize() that's not supported by JSON might be required (e.g. exporting classes)

Hey NoDiskInDriveA,

Thanks for the contribution! I'm not sure if there are any issues with exporting JSON, but I'll have a look this week and get back to you.

Hey NoDiskInDriveA,

My apologies for the delay! The PR looks good, but I worry about having two export buttons from a UX standpoint. WordPress typically handles data in a serialized format, so I'm opting to stick with that as the default. Maybe JSON exporting can be enabled with a define?

Let me know what you think.

@NoDiskInDriveA I really love this! I've been making a bunch of Theme Presets for my clients and customers and having a JSON file to modify is so much easier.

I'm currently using an action on save to automatically import a exported .dat file with some settings. I would love to switch to JSON import, but I have no idea how I would need to modify my current snippet! Here's what I have now:

It would be extremely awesome if you could help me get this snippet working with your JSON feature :-)
