Edit customers info on shipped orders

[ShipCNG]

This was a feature before the new layout took effect and is a requirement to have to function efficiently.

Having the ability to edit customer's info such as phone numbers & email addresses on shipped orders is a must-have. To many times either the customer or shipee transposes data leads to customers not getting their tracking info. 

This is a simple but most useful feature and I'm unsure on why  it was removed.
