Improve shipment tracking

[Michael-Herzog]

At the moment, you always have to add the tracking URL for each shipment, even though it never changes.
It should be possible to save these URLs somewhere (including placeholders, e.g. for tracking numbers, which are then resolved).
Perhaps directly with the shipping method.

The PayPal system name for the shipping service could also be saved there.
This is the only way to ensure reliable matching at PayPal and to enable more PayPal functions.

Don't reinvent the wheel, See IShipmentTracker and #1149.

I already had in mind to take a closer look at this. When looking at this issue. But of course it's better to write i down where it belongs: in this issue.

Hi there, Do you think you can enhance this to take multiple tracking ID's ? Sometimes we have to send 2-3 or more parcels for one order and their ids are different....(the main url does not change for many shipping companies but usually the id of the shipment is in the query of the url)? This should also generate multiple tracking links in the user email as well...
