[FIX] point_of_sale: prevent the company logo from being cached by the browser by accessing it via a random URL
[FIX] models: in method onchange(), check for record dirtiness only on *2many fiels

Cascading onchanges can be caused by a related field computed in cache.  This
causes a bug in sale order lines, were setting the uom field forces reading
product fields, which are inherited from product templates.  The inherited
fields are computed as related fields, which marks the product record as dirty.
This subsequently triggers an onchange on the product field, which resets the
uom field!

[FIX] product,purchase,point_of_sale: force empty values for dropped fields

At 96f038a product-related fields were removed due
to an important product.template/product.product
refactoring. As the field values were simply
dropped, they may not be nullified when upgrading an
existing database. Forcing them to False will take
care of it.

[FIX] models: in onchange(), do not send a field value if it has not changed

The method onchange() executes onchange methods in cascade.  Suppose onchange()
is called and a field F=1 in the form.  If an onchange method set F=2, that
value is put in the result variable.  If another onchange method set it back to
F=1, the binding F=2 must be removed from the result variable.
