[IMP] display breadcrumbs content in browser tabs

this change is simple, except that many actions display a form view in
'create' mode to edit some stuff (for example, most settings forms or
the 'Your session' action in point of sale).

As a work around, we use
a simple heuristic (nice word for horrible hack): the title displayed
is the title of the action if we have a single form view.
[IMP] product: search on internal reference

When searching on the name of a product.template, search also on the default_code. Move the filter from product.product to product.template.
The field default_code is on the product.product but accessible through a related field, meaning when reading it will fetch only the first variant but searching on all variants.
Fixes #3399
