[MERGE] orm: avoids error when reading twice a field

_read_flat: remove duplicated fields in read call
get many2one: as False is instance of int, check the value of x first to avoid calling a name_get with a list of False

When we were reading twice a m2o field where at least one result is null, the first call to name_get would set the value to False instead of None and then accepted by the filter 'isinstance(x, (int,long))'

Wwhen parsing a integer field, do not accept float values. '1' or '1.0' is ok but not '1.1'. (opw 608544)

sale_order module override state field of sale.oder (sale.sale.py) and forgot to reset the track_visibility, therefore sale orders state changes are no longer tracked once this module installed.

This will make sure already processed rules are persisted
in case a timeout occurs while processing the next ones,
ensuring that *some* progress can be made in most cases.

A safety guard already in place prevents the recursive
trigger of rules while another rule is being executed,
as a simple measure to prevent endless loops.
This guard was missing when processing time-based rules.

A programming error introduced at rco@openerp.com-20121220142445-emzzvhlw400q37c9
fails to properly check when a rule has already been executed in the past.
Time-based rules should only be executed if the trigger date is in the past and:
 - either they never executed before
 - or the last execution date is older than the trigger date

Executing a rule always updates the `last_run` value, which would
always force a useless registry reload to occur. Only signal the
change if the rule applies to a model that was not previoulsy
monitored for base action rules.

The field note on account.fiscal.position and account.fiscal.position.template should not be translatable in classic modules.
The l10n_multilang module is intendend to make chart of accounts multilang and is the place to set translate=True

[FIX] delivery: do not remove the delivery method on the sale.order when adding it as an order line (useful information)

If the writeoff_amount is above 0, the fields writeoff_acc_id can be displayed and is required depending of the payment option. If the writeoff_amount is reset to 0, this field should no longer be required.

[FIX] orm: do not recompute m2o stored function field at read.

The get() method of m2o function fields is used for 2 different things:
 - call the function defining the m2o
 - get the name_get representation of the value

Until this pathc, only the first case was handled, resulting to a useless
recomputation of the field when reading it.

[FIX] ir_cron: use the same search criteria as when listing job to excecyte when acquiring the ock on the job before its execution to prevent running already executed job

[IMP] stock: when checking the state of the product, do not recompute the quantity on every move but only the one currently browsing (optiomisation)

User should be at least have Configuration settings group to be allowed to create actions. Basic document page users do not have this rights, therefore we temporary give superuser_id to create the action

This is related to rev 133c5033

Triggering an empty write could break constraint (can not update past timesheet) (opw 606963)

When uninstalling a module, remove the ir.model.constraint after removing the non-model records and before fields and model definition.
Without this fix, some constraint would be removed too early allowing to have broken relations and data left from removed module.

The default value should be called with a lambda otherwise the payment_date is set to the date the server was started (opw 606715)

When creating a grouped invoice, the invoice_vals value is used to create the invoice line.
The value was not reset for grouped invoice and we reused the values of previous line.

Some browsers (e.g. chrome) trigger onEmptyClick as well as
onBeforeLightbox during drag&drop which calls two slow_create
calls (and two popups). Workaround to kill the second one.

[FIX] mail: detection of MIME type

When parsing the mail headers, the content-type may has a 'type' attribute for Multipart/Related  objects (rfc2387).
Previous check would match on attached files of type text instead of real `content-type: text/`.
