The `unittest2` package is simply a backport of `unittest` from the
Standard Library of Python 2.7 to previous versions.

There is no reason to use it any longer.

Closes #6941

[FIX] mass_mailing: Display attachments in a proper way
[IMP] mass_mailing: set default value for popup_redirect_url, as it's sometimes required

Also, we should be able to set a customer on a project, whatever the access rights,
for example, if we're managing services by using internal projects.

Modify test test_ir_values.py also, as the action was used in it.

When creating pos_orders from the form view, tax_ids on the
pos_order_lines were never set.

This was kind of fixed in 53278693. But
in there it was in onchange_qty, because the way the fiscal position was
taken into account required it to be. Because we take the fiscal
position into account in a different way now we can assign the taxes in
onchange_product_id which makes a bit more sense.

Allows a user to set multiple fiscal positions per pos_config. Orders
created on that config can then be assigned one of these fiscal
positions. In the POS this can be done through a button that will appear
above the numpad when fiscal positions are set on the pos_config.

Revert "[IMP]point of sale: added fiscal_position_id field in pos config to set fiscal postion on each shop."

This reverts commit 53278693.

Reverting this because we would rather want to be able to set a fiscal
position per pos_order, not per pos_config.

* Adding a new group in a group of fields is breaking enterprise layout
* Moreover the group was useless: useless colspan, unique field with
colspan>>>col in it, double access-right, ...

Calendar height was again a problem since the introduction of the
bootstrap layout (the .row had not height 100% and thus the calendar
was not able to compute its height anymore).

[FIX] account: 'invoiced' button on partner now opens the tree view of customer invoices instead of the vendor one

This is a partial revert of 132dcc97. Indeed the
hr_equipment module can be used to track any kind of equipment, not only
IT assets.

Category is a classic m2o, not a statusbar. Moreover fixed category_id being twice
in the form, leading to one of them being impossible to use.

Before: if a user blur a editable area without editing, the editor is removed and all bind are remove.
The 'content_changed' bind are removed and the 'o_dirty' class is never apply.

On webclient, on 'Attachment(s)' dropdown (form view) when clicking on an attachment to download it, a request is sent to /web/content/ with a param 't' containing the current date. This param wasn't used neither before the new controller, but the old one accept additional kwargs. The new controller crashes, and since the t parameter is not used, removing it seems better.

Using website_mail mecanism will prevent to transform POST params into GET params when redirecting. This will reasure xmo ;)

Transform POST param into GET param when redirecting to login page can cause security issues. Now, instead of displaying textarea (even if public user) and the redirect to login page keeping written comment, we display the login button with a redirection to the page to comment.
The redirection happen before commenting, avoiding to remenber param such comment text, rating, ...

To post a comment, the user must:
- be connected
- have a token
- or have a sha_sign

This reverts commit 7974bf54.

[FIX] stock: lots (re)reserving should handle quantities correctly and better handling of reserved quants without lot

When moving pack operation with lots:
The system will still take the quants that are reserved with lots first.
What changed, is that, secondly, it will take reserved quants without lots.
Afterwards it can use the traditional methods to check the non-reserved quants for every lot.

The name_get has been updated accordingly : if an address has no name, we now show parent_name, res_partner.type.
The contact template shows the name when it exists, and the parent_name if it does not. This should produce cleaner reports.

Though the name field is no longer required on the res.partner model,
"required" attribute in views and an sql contraint enforce that all contacts have a name.

Print 4 barcodes per page, in a disposition that is practical to print on stickers.

- dates are editable even in confirm state. Only events in done states are
  not editable.
- the print badge button is actually a button to edit badges, so let us udpate
  the name

Originally written by Nicolas Seinlet <nse@odoo.com>. Provides
pos.config with a product.product cache.

This adds a ported and refactored pos_cache from odoo-extra:

- Adapt to changes in web and point_of_sale since 8.0
- Refactor the load_server_data function, so it isn't copy pasted but
  cleanly patched into the load_server_data super.
- Make the cron inactive by default.
- Also remove retrying the write 5 times, when it fails we'll just have
  to wait until the cron triggers again (an hour from then).
- Store the product.product fields and domain on pos_cache. When cache
  is requested from the pos with a different field or domain it'll
  automatically recompute. Necessary for when someone would install a
  module that modifies these things in the pos after a cache has been
  generated.
- Have multiple caches per pos_config per user
- Make the module adhere to the Odoo Coding Guidelines.

Also check for plus sign only to be visible when necessary,
which makes quantity unnecessary when handling serial numbers

The function field selected_seller_id is removed  and must be replaced
by a direct call to method `_select_seller`. This is more conventional
than the previous 'browse with context' way of doing.

We introduce a new field on supplierinfo: product_id. Thanks to this
field, the vendor information which will be used in a purchase order can
be specific to the product variant.
