Now it's possible to configure if the portal RMA request form is loaded
in a popup or in a single page.
In that page, we can add custom blocks (if the website is installed) a
customize the form text.
In this commit, we also add the possibility to extend the form view to allow
custom fields that will show up in the RMA description.

When a sale line has a phantom product (mrp kits) the RMA would not be
possible as the wizard couldn't pair the components moves with the
product in the line. With this approach, we can at least return the
spare components of the original kit line.
We also need some hooks to intervine in the main methods, like in
invoicing.
