Info Select & Rendering responses JSON

[joguSD]

Implements an Info Select interaction that will show the full JSON body of whatever option you're currently selecting in a similar fashion to the docs pane. I held off on adding this because I was unsure about how to safely render the responses as JSON because the json.dump method couldn't handle datetime objects. It seems the CLI also had this issue and implemented a json_encoder util method to handle it. I've refactored the wizards to use this in all places where something is being rendered as JSON.
