Display Started Date as well as Completed Date on Street pages

I think it would be interesting to add the “Started Date” to the individual Street pages. This would be the date on which I’d completed at least one node of that street. We already have “Completed Date” and for most short streets the two dates will be the same.

For long streets (such as the Southern Transit monster in Wiltshire) it takes multiple visits to complete all the nodes and it would be of interest (to me at least!) to have a record of how long such a completion has taken.
