Meet a bunch of fresh changes for the paywall editing page 🍋 

1. Remote config now has a table view in addition to JSON.
2. You may set types, key names, and values, adding data row by row.
3. We are checking your data to be a valid JSON and showing warnings if it goes wrong.
4. Upload a screenshot, and you'll see it in paywall metrics by hovering on the paywall's name. This eases navigation between multiple paywalls and versions. 
5. Now you can see the current version number on the editing page.
6. Use the check box "create new version" to save your edits for the current version or as a new one.
