Support bulk-editing headers

[infinitely0]

In Postman you can edit headers in bulk, which is very useful in cases where you want to paste the headers of a previous request and amend the body, for example. In Restfox you have to insert the headers one by one.

I don't expect this would be too difficult to add. You'd just need to parse the line-separated headers in a textbox and update your list of headers.
