Rework link property configuration system.

This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters. As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

Add another "reuse" permission, to distinguish between the case where a

source filter will simply want to re-output the same image multiple times

times.
