[IMP] product: Order product.template by name

When no order is forced, it's more user-friendly if the products are ordered by alphabetical order.
This will mainly be applied:
* In the list view in the back-end
* In the eCommerce, for products with equal website_sequence
[FIX] point_of_sale: display an error when trying to print a receipt on an outdated posbox
[FIX] website_sale: typo in tour
[IMP] crm: Use cookies to save utm instead of session.
[FIX] web: invoke fields_view_get with kwargs instead of positional args

The mapping old api → new api mistakenly takes the last positional argument as
the context (fields_view_get() has an extra parameter after context.)

[FIX] mrp: force empty domain to reset action at upgrade

to empty during upgrade, as the MRP BoM model
has changed.
[FIX] openerp/osv/fields: disable prefetching when reading inverse of one2many fields

This fixes issue #2146.  The inverse of a one2many field can be an inherited
field (_inherits).  In that case, we cannot read its value with a simple
database query.  Instead, we let the related field read it, but for performance
considerations we disable the prefetching of other fields.

[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] point_of_sale: chrome was dropping the cookie when loading the company logo, resulting in an incorrect logo in multi-db setups.
[FIX] mrp: force empty values for fields that were dropped

This ensures the field values are cleared during
upgrades from previous versions
[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.
