[IMP] doc-ws: prepend setup code when copying from a snippet
[FIX] product: name_get of product.attribute.value

name was confusing for bom and product if the value of the attribute is display without the attribute name
added key in context to keep the previous behaviour (e.g. in product view where the attribute name is present)
[FIX] mrp: The attribute on bom lines is not filtered in function of the selected product template
