FileDownloader error handling

FileDownloader is great so far and I would prefer to use it instead of our custom solution.

As there are unforseeable reasons for a download to fail, it would be great to be able to handle those cases gracefully. Currently, surrounding the node in a Try region does not help.

Also, the message of HoldLatestError inside FileDownloader could be exposed as an (optional) output pin.

Examples.
