Adding new value in the information about manufacturer

Summary:

We need to customize the information of the manufacturer, in particular we need to add a new unique number value.

So we need to have in the page of the manufacturer the usual information ( name, description, adress etc.) plus one text box, let's call it ID

We need to assign some specific value to every manufacturer already created and for the new manufacturer we need a consegutive number starting from the biggest number.

We could customize the manufacturer parts, but not the manufacturer page.

In case this is not possible we need to renumber all the exsisting Registry ID.
