[FIX] stock: correct label for picking_id
[REF] stock: replace <div> in view by nolabel

This patch does not change the look of the view; it is only intended to
use the standard feature "nolabel" instead of hacking the HTML with a
<div> tag.
[REV] stock: partial revert of 52c3b52bf09fea7e0920ebcec3f0e8acb066b2b7

The <div> were introduced to correct alignement issues in this form view. Actually, they are generic and due to inherited invisible group, so CSS is sometimes incorrect when you hide groups. Should be fixed in form view implementation.
[IMP] allow many2many to specify formview (web client)

One2Many fields can specify sub tree and sub form view, to be used when
displaying a list view and when adding/editing an element.  Many2many
can display a sub tree view, but ignore sub formviews.  This can be
fixed by specifying an alternative_form_view to the popup form widget.
