Enable Sync jobs to also schedule exports

Yes this would be very useful. I propose to create a new Job Type called Export Job. The fields for this job type would be: Dataset ID, Export file type, Export file location

The Export file location would be a selector (with a Browse... button). Then the user could either select a directory or a actual file location. If they selected a directory it would output file with default name to that directory. Otherwise it would write directly to the file the selected (overwriting any file if one existed). We need to ensure the user is aware files will be overwritten.

Ideally the tool should support exporting to all formats supported by the UI.
