Updated UI for S3 Extractor and CSV Import

We have updated the UI for the S3 Extractor and the CSV Import tool. We're keen on trying new things to improve your user experience with Keboola Connection and hope that these improvements offer a simpler and easier approach to editing your component configurations.

There is no difference between editing and non-editing state, everything is directly editable and the state of the Save button indicates if the configuration has been changed or not. 

If this approach proves useful and stands the test of time, we'll carry it on to other components as well.

Let us know what you think!
