[IMP] base: no default domain for partner's title

The title field should not have a domain by default.
When a new record is created or the 'is company' field is changed, the onchange_type is triggered to restrict the domain accordingly to is_company field.
When an existing record is modified, there will have no domain on title field. It's not ideal but at least companies will be able to change the title without the need to modify twice the field is_company.
Fixes #1713
[FIX] Fixed the issue of calendar view reload events inconsistency, when the slow create popup creates event through any form button which is kind of object, action or workflow at that time events are reloaded but still button action is not called like workflow is not triggered and hence state of the event is still not changed and due to domain newly created event is filtered, note that events are refetched when create_completed is triggered and create_completed is triggered right after creation of record, but there are case where some form button changes state of the record and it requires to refetched for example we have scenario in mrp order planning where Confirm Production creates event but before workflow is triggered and state of the event is changed, events are reloaded and newly created event will not returned because of domain.
[FIX] account: reconcile: no useless revalidation

Avoid revalidating the complete account moves
that contain the lines being reconciled.
The reconciliation does not change the validity
of those moves anyway.
This represents a very important speed up of
reconciliation when moves with several hundred
lines are involved.
[FIX] stock: inventory lines with no production lot: compare with correct stock level

Inventory lines without production lot number should
be compared with the stock level of products without
a production lot. Otherwise the final result of a
validated inventory is wrong as soon as there are
lines with and without production lot for the same
product.

Adds corresponding regression test.

[FIX] web: do not focus if the focus_field is not a field

Sometimes, focus_field could be a button, and in such cases, we should not focus on it

[FIX] point_of_sale: field date of report.pos.order should be a datetime

The date_order field of the pos.order is a datetime, not a date
As, in report.pos.order, the date field is related to date_order of the pos.order

We usually do not commit fixes altering the model fields structure in 7.0, but this one is retro-compatible, as the database structure won't change
[FIX] product: make sure unlinked product still exists

When uninstalling/updating a module, we may execute unlink method on product.template before product.product. In such cases, the product is already removed after removeing the template (_inherits) and the chained unlink of the product would fail (traceback when browsing).

[FIX] account_analytic_analysis: quantity overdue on quantity exceeded, not reached
[FIX] account_voucher: avoid error if no partner

The field partner_id is not required on an account.voucher but the validation was failing if none was set (opw 611663).
This patch makes a fallback on the account of the voucher if neither a partner nor a writeoff account is specified.
[IMP] account_voucher: make the field tax_amount always readonly

The field tax_amount is fieled with onchanges and the compute_tax method. Setting a different value than the one computed by the system may lead to unbalanced move (which is obviously wrong).
In the future, handeling these operations by setting the correct value to the tax accounts would be better.
[FIX] sale: define sale_note field before using it as a default value for sale.order

When uninstalling/installing sale module, this can be problematic
[FIX] account_voucher: wrong type in context

The type 'general' no longer exists on a account.voucher. As in general context, removed the default value on this menu.
Fixes #1261, it produces a traceback in 8.0 where the selection fields are less fault-tolerant.
[FIX] web: rendering issue in mail composer on Firefox

The cleditor width does not include the margins. Setting 100% will make the editable area too large (104%) on Firefox (opw 611700).
Replaced by auto, the default value adviced by CLEditor.

[IMP] auth_oauth: set default 'zocial' css_class

The buttons for new providers needs at least the zocial css class to be seen as button. As the field css_class is not in the default form view, add it by default.

[FIX] purchase: skip move if not linked to a purchase order

When this situation happens. the 'cost' is None and the web interface cannot handle this value, provoking a JS error. Thus, prefer to fallback on the standard way to get the cost: based on the current standard price of the product.
