Dropbox Node about node-red-web-nodes

The out node should be consistent with the File Out node.

• it should be possible to provide the complete filename in the node itself (optionally overridden by msg.filename)
• it should provide options to both overwrite and append to the file

There isn't an api to do appending so you'd need to download the current copy, keeping it locally and upload the whole thing each time you extend it, so I'd be inclined to not support that?

Regardless, I agree we should aim for compatibility between dropbox/s3 file upload and file out and clearly document any differences. That is what I am currently trying to do. I wanted to make a start on the s3 node to better understand the different APIs before trying to define the common interface.

For instance, having looked at the s3 api, I'm cautious about supporting the payload option since, although it seems natural with the dropbox api, for the s3 node that would mean you'd need to write to a temp file first which seems a little inelegant.
