[FIX] stock: groups mixup in views

Use group_production_lot for serial options, group_stock_packaging for packaging, use group_tracking_lot for pallet/parcel
Groups are removed completly from the view for stock.tracking as they render the view useless.

Always display weights on the product form
They really have nothing to do with the logistic units and we don't have another group to restrict them to.

Fixes #1443

[MERGE] forward port of branch 7.0 up to 03df412f
[FIX] website_sale: save the company in street and the street in street2.

The old behaviour was not better, because when we print the invoice, the order was ugly:
    Name
    Street
    Company name
    Country

Now we will have:
    Name
    Company name
    Street
    Country

This patch is not retro-compatible:
   Old partners will see the address in company name and vice-versa.
   Need to update view and switch street field and street2 field

Revert "[FIX] Error when installing module document"

This reverts commit 8dd4c83d9cf6f45ca39f120b296c1c69079154a4.
It does not fix the issue, but hides it instead.
An actual fix has been made since.
[FIX] website_sale*: handle no delivery methods in website

[FIX] openerp/osv/fields: fix method to_field() to pass some falsy parameters.

For instance, the attribute copy=False was not passed when converting the
_column to a Field.  Simply make sure those parameter are always passed.
[FIX] fields: in to_column(), returning self.column is generally not correct

Consider the following example:

    class Foo(models.Model):
        _name = 'foo'
        _columns = {
            'state': fields.selection([('a', 'A')]),
        }

    class Bar(models.Model):
        _inherit = 'foo'
        state = fields.Selection(selection_add=[('b', 'B')])

The attribute 'column' of the field does not have the full selection list,
therefore the column object cannot not be reused, even a copy of it.  The
solution is to systematically recreate the column from the field's final
specification, except for function fields that have no sensible way for being
recreated.
[FIX] purchase: do not pass uom in product_id_change when changing of product
