erp5_web_renderjs_ui: keep previous focus color

This reverts commit a87db49b.

Most ERP5 web sites use a global form wrapping the content.
Modify the html viewer to not drop this content.

Stop using ck_editor in read_only to display HTML.

This allows to get rid of the ck_editor iframe, allowing a faster load and removing the iframe scroll.
The maximise button is no more needed in such case.

It also removes all ck_editor links handling: links can be open in another browser tab now.

This changes impacts both xhtml style and erp5js.

This gadget take an HTML string as parameter.

It first cleans it up (with hardcoded behaviour currently) by dropping unknown tag elements, unknown/unsafe tag attributes.
It is another protection layer on top of asStrippedHTML inside ERP5.

Then, it displays the output HTML and style it with an hardcoded set of rules.

erp5_ui_test: check empty percent

fixup! erp5_web_renderjs_ui_test: cover case of orange highlight not displayed in rjs_gadget_erp5_emailfield_js with test

erp5_web_renderjs_ui_test: cover case of orange highlight not displayed in rjs_gadget_erp5_emailfield_js with test

store error_text to be propagate to render()

This allows crawlers like wget to also fetch the rendering gadget without executing any JS

This will be needed for DCWorkflow to ERP5Workflow migration so this will be
a core Document and make bootstrap easier.

Nowadays Line Report works fine in ERP5JS. It is also useful in context of MRP.

See merge request nexedi/erp5!1347

This shows the asset price from `stock.total_price` which can be just the
movement prices or the evaluated prices if getDestinationAssetPrice and/or
getSourceAssetPrice type based methods are defined.

erp5_trade contains Base_viewTradeFieldLibrary which contain
my_dialog_mode_portal_type, which is a multi list field where user can
select multiple lines portal types. It is used in
DeliveryModule_viewDeliveryLineReportDialog/your_portal_type

erp5_item also contains Base_viewTradeFieldLibrary , for cases where
erp5_item extend trade module to select items. It also contains a
my_dialog_mode_portal_type field, where user can select item portal type.
That field is not a multi-list field, but a list-field. It is used in
DeliveryLine_viewSelectItemListDialog

So when erp5_item is installed, it overrides
Base_viewTradeFieldLibrary/my_dialog_mode_portal_type with a list field
instead of a multi-list field and breaks
DeliveryModule_viewDeliveryLineReportDialog, because user can no longer
select more than one portal type.

This renames the field in erp5_item, now we have:
 * Base_viewTradeFieldLibrary/my_dialog_mode_portal_type for movement
portal types
 * Base_viewTradeFieldLibrary/my_dialog_mode_item_portal_type for item
portal type

Until now it was only used in ERP5Catalog where the expression property is
`expression` for both Python Script and SQL Method but this is a common pattern
and will also needed for ERP5Workflow.

Instead of generating the report in one big activity, split the calculation
in several batches, so that the processing can be distributed on zope nodes.

The limit for the number of lines was also increased from 10000 to 100000
