Proposal: Add JSON format button

[WTIFS]

Hi there, I'm planning to add a JSON format button under the configuration value textarea. As some of our colleagues use compact JSON format, and it's hard to see the differences when publishing.

The button will be looked as follows. Do you think it's a good idea?

Scene	before	after
Text Mode
Properties Mode
