suppliers don't relate to product variants
I created a very simple product with variants on demo4.4.tryton.org
called 'PRESTO 605 sur plage'.
The variants are 'Eau froid' and 'Eau chaude'.
I created two suppliers each providing both products.
Unfortunately the suppliers codes seem to always map to the first variant
'Eau froid' so it is quite apparent that there should be a means to
relate the suppliers products to the correct product variant.
Though it seems that it has been mentioned before, there is a missing variant
specific name needed, though the description seems somewhat there.
