For two reasons:
- In previous version, query would lose Embedded Documents, lacking a left join in follow_up_uid
- In large instances the previous version was many times slower

Also,
erp5_dms: Add a test for Base_getRelatedDocumentList

To check it works correctly with both related (follow_up)
Documents and with sub-object Embedded Files

When IBAN is defined, use it by default for reference. IBAN is used by
default all over europe, so when it's set it should be used by default for
reference.
Mixing IBAN and other properties does not make sense, so this change
should not have unexpected side effects.

We also update "edit_order" on BankAccount_view so that title properly
fallbacks on reference when reference is iban.

To ease "manual" (ie. not from payment rule simulation) creation of payments,
update "create relate payment" so that it suggests the payment mode and the
payment date from payment conditions of the invoice's trade condition.

Use editor gadget to render the output as raw data.

Use the page class to improve xhtml style rendering

* enable more elements/attributes
* show table cell's border
* reduce table width
* support align="center"
* only use sans-serif font like ckeditor

erp5_ui_test: textarea use an external validator as required prevent submitting

Avoid propagate empty value to change_state and only set new value if it is in modification_dict

This introduce a new utility script Invoice_getPaymentDueDate and removes
the previous attempts, SaleInvoiceTransaction_getDueDate and
TradeCondition_getDueDate that were never used.

- Column Version length is extended from 10 to 255 so it can store md5sum's lenght (32 characters) that is needed by data streams created during ebulk tool ingestions used in wendelin.
- New column Size is needed to speed up ebulk tool and can generally be useful for DMS, so that we can search/sort document by size.

File is a top-level module document, like PDF, Text Document etc, so it
should have its own security definition and should not acquire local roles.

For cases where files are embedded as sub documents, we are using Embedded
File, which acquire local roles.

In "Attach document" action of erp5_ingestion, the default publication section of attach document suggested in the dialog is defined by a type based script.

We could do the same for group, so that we have a script that is easier to customize for specific cases. One use case is for accounting transactions, the group is usually the group of the entity where the document is attached.

Also, we could enable type based script in document scanner dialog, which is very similar to attach document dialog, but it was not using the scripts.

Similarly, we introduce a script to suggest a title in document scanner.

Another difference between "Attach Document" and "Scan Document" is that the later had a "publication state" field, allowing user to choose a state for the created document. We extend this to "Attach Document" as well and introduce another customizable type based method to be able to configure a default value.

See merge request nexedi/erp5!1359

They are often used to achieve surprising styling

This customizable type based method is used in "Attach Document" and
"Scan Document" dialogs, to set a default value in the dialog for the
publication state field.

This code is not used and rely on pdftk that we don't have installed in
slapos

Do not remove relative url, as they are ofter use in img tag

This allow to see the content when being displayed as a web page content

details is not always the last child

Extend "Attach Document" to have the same feature as in "Scan Document"
so that user can directly choose the state when uploading a document.

This simplifies a bit document_scanner, which can reuse the code that is
now in Base_contribute

document_scanner: introduce a customizable type based script to suggest a title for scanned document

Unlike when we attach a document, where the title comes from the filename of the attached document,
when we scan document we don't have any filename. There's a default behaviour of using the current date, so that title is not empty, but in some cases we can define a script to suggest a better title, for exemple when scanning an invoice, we can suggest using supplier name and the invoice title.

ingestion's dialog uses some type based methods for customizability, use
same type based methods here.
