fc_download_data should check local disk for data more intelligently

It would be best if it used e.g. url header to decide whether an update was required
Partial solution here 7f99c16. But it would be better to check at a minimum date/file size or ideally to cache the header including etag along with the file so that it can be checked.
Could add a second file called e.g. .myfile.rda or myfile.rda.info alongside myfile.rda with metadata that improves on etag if that won't work. A bit clunk, but fine if we are looking after things.
fixed in commits mentioned above.
