The idea is that a week after the user starts using Subsurface we ask them
if they would like to submit a survey response.
If you are running a development build, don't wait seven days.
This patch doesn't do anything with the user's selections, doesn't submit
anything to our server, etc. It's just a placeholder to tune what we
should ask, etc.
