Allow users with no trailhead data to "skip to download"

[alanjosephwilliams]

Currently, we only offer users the ability to download a zipfile of OpenTrails data once they have completed both the trailsegment and trailhead shapefile upload-and-transform process. We should provide a "skip trailheads, let me download my data now" option for users with no trailhead data.

Moreover, with today's amendment to OpenTrails v1.0, trailheads are not directly associated with segments via a "segment_ids" proeprty, which contains values found in trail_segments.geojson's "id" property. For those who have uploaded trail_segments to the converter without unique ids, there could be a use for downloading the converter output, associating trailheads, then uploading trailhead for conversion.

Perhaps a "skip this step" button, so they'd continue to move through the process? Rather than a download shortcut.

That makes sense to me, certainly. I think I can implement this, so I'm assigning to myself.

Next time I'll make that kind of update a feature branch.
