Feature: Export Tables as JSON

[hecon5]

As I run into edge cases and see others with TDF exports and Access's issues with XML #80 #80, #305, #314, et. al., and I was thinking maybe another (also with its own caveats) way to do this is with modJSONConverter, and just export the table as JSON.

While this is no small feat, it is a nice balance of Human-readable and "We don't have to build all the tooling ourselves" inbetween land.

Thoughts? I'm experimenting with this for an internal application, and if I can get it to work, I'll put it up as a PR, but thought I'd toss out the idea in the case someone else has already tried it and found out it's a road to avoid.

This is related to #250.

I think, given XML's more "truthy" file export, and that we're not trying to use the export as an analysis tool, JSON may not be the way to go here.

I'm going to close this as a result.
