Display a ParallelList field as a list of sub fields calculated with the hash script.

Keep previous HAL properties to keep compatibility for client without the JS implementation.

This should have no impact on existing code as pylint is ran on a named
temporary file anyway but it avoids useless checks for relative imports
and thus is slightly faster.

See merge request !1144

This is something we can do in TALES, it was supported in the old UI, so
we keep compatibility in HAL JSON API.

adjust tests now that the test component itself is found by catalog.

* Import Movement Document:
  + Event
    + MailMessage
  + Project
  + ImmobilisationMovement
* Imported by IMovement:
  + IAccountingMovement
  + IAmountGenerator
    + AmountGeneratorMixin
    + AmountGeneratorLine
  + IAssetMovement
  + IProductionMovement
* Used by MovementGeneratorMixin:
  + IMovementGenerator
  + IMovementList

Also, define providesI<INTERFACE_NAME>() on Base class for migrated Interfaces as
these needs to be available before bt5 containing the ZODB Component Interfaces are
upgraded (see also c86107bf). Otherwise, testUpgradeInstanceWithOldDataFs fails as
z_catalog_item_list (newActiveProcess() from upgrader) calls providesIMovement().

This also moves ImmobilisationItem and its interface from erp5_immobilisation
to erp5_core as ImmobilisationDelivery import them.

* Discount: Portal Type actually uses Resource Document.

We were only checking if the defaut charset or default collation were
same, but if anything is different in the table options, we should
update it.

Also add a missing test for updating column comment

Not a proper tool to search source code, but makes it possible to search
for source code in component.

test_apply_model_filled_computer_batch_mode did not pass batch_mode
and was wrongly checking that result is True

Test was passing, because without batch_mode Computer_applyComputerModel
returns Base_redirect, so the result is indeed evaluated as True.
Yet in this case we should expect False, since no changes are applied

this is required for stock browser to work in ERP5JS with Component
portal type

and make it possible to create the test delivery using a component as
resource

Do it once, after any business template deletion and install happened.

Several bug fixes for business template update bugs, including a fix for the problem preventing to update erp5_accounting_l10n_fr

See merge request !1112

These new versions contain several small improvements.

It seems this version of prettier formats javascript in a way that jslint does not complain about.

Also contain some small fixes for our renderjs and rsvp type definitions, so that monaco-editor-gadget.js can typecheck.

See merge request nexedi/erp5!1139

* "Create Skin Folder" action had a typo, so it was not setting the `business_template_skin_layer_priorty` property that business template is using when installing.
* "Create Report" was not updated for the new "action title" feature of forms.

This time, add the missing tests that should have prevented these problems.

Enable coding style on erp5_forge, after removing several problematic scripts that did not seem used.

See merge request !1134

This is not supposed to happen and can hide errors.
