Store return address and informations

New feature :

Add a way to display informations about return to customer (how to return products, where to return etc).
This informations aims to help customer to answer questions like where i have to send my return ? how can i make a return ?
For example, someone which just send product without informations make hard to find why this product is back to store. With "Return store informations", Store owner can explain which document customer has to join to his return (order copy ? return copy ?)

What i suggest :

In first time, an easy way is to make to textarea settings fields in return settings page to edit "Return store informations" and "Return store Address".
This informations are added on new return form and returns list.
