Clarify abandoned payments

Created by: artfulrobot

If someone fills in a CiviCRM Contribution form and clicks through to the GoCardless external website but then abandons the process, CiviCRM is left with a "Pending"/incomplete Contribution and Contribution Recur record.

However, if they complete the process, the contrib and contrib recur records still show this in their status, until the first payment has been successfully claimed, at which point the recur record is set to status: "In Progress"

It might be clearer for CiviCRM admins to see the recuring contribution set to "In Progress" at the time that the mandate and subscription were successfully set up, since then any "Pending" records that are older than an hour or so could be assumed to be abandoned processed, and could be ignored (or have their status set to cancelled or such).

Would this help you? Does anyone want this feature? Might anyone want to contribute to making it happen? I think there's perhaps 3 hours work in it, including updating the test code, documentation etc.
