mqtt-sonoff crashes when colink.conf is not present

mqtt-sonoff crashes when colink.conf is not present. (I fixed that, will submit pullrequest)

colink.conf is expected at /mnt/mtd/ipc/cfg/colink.conf

But that file does not exist. Maybe that file will be generated once the device was configured with the ewelink app? Does anybody know?

Could somebody maybe provide a template for that file, so i could add code to generate the file if not present?
