partial fix for failure to sync photos - appears to be memory exhaustion and dependent on filesize although an unrelated issue was found with directory creation during file sync (we didn't check ownership when looking for duplicates).

This checkin provides the means for a sync process to fetch the contents for various photo scales from the original server just as is done for the attach data now. It is still missing the bit for the sync process to spawn a mob of children to fetch these suckers and update the photo table with the results.
