Item Lables on Transports

We should be able to add item labels onto transports. This would be extremely helpful when making Blueprints as it would be easier to see what needs to connect to what. This is something that DSP and Factorio allow you to do, and I think it would be a great fit here too.

Great Idea!! Im surprised i didnt think of suggesting it first :)

The icon already appears on storage units, why couldnt it just transfer the icon from the unit to the end of the connected transport.
