this 'relative_url | ascending' sort can lead to killer queries and it is of no use

This fixes a problem that a broken image like

    <img src="?quality=75.0&amp;display=thumbnail&amp;format=png" alt="Image">

was displayed when no image have been uploaded.

This was working fine on product, this makes component aligned with
product for this field.

This fixes errors such as:
E: No name '_dtmldir' in module 'Products.ERP5Type' (no-name-in-module)

Where _dtmldir is 'PATH/TO/Products/ERP5Type/dtml/', dynamically added to
Products.ERP5Type module.

Because most of the times we configure roles so that users assigned to a group can only see documents from this group, it's a better default that in reports they can only select the groups they are affected to (and the sub categories of these groups).

For more complex security configurations, the script `Base_getDialogSectionCategoryItemList` can be customised.

"Split and Defer" action

![screenshot of split_and_defer transition](/uploads/2a9d4efc139b881bfec82a425996c659/image.png)

functionality can be achieved with "Solve Divergences" action with a "Split and Defer" 

![screenshot of solve_divergence transition choosing split and defer action](/uploads/704c4713d842455c4e369a99d8f4867a/image.png)

we don't need two ways of doing the same thing.

This removes the workflow transitions and the dialogs and update the tests to use the "Solve Divergences" action instead.

See merge request !1148

Main goal was to make erp5_trade 100% translated, also the divergence explanations.

The result of the solve divergence dialog is:

![solve divergence dialog in french](/uploads/7ba5d3fcccb58b223471566d528c5c0a/image.png)

This also fixes a few small problems with existing translations

Fix a problem with `WebPage.getImplicitSuccessorValueList`, it did not detect references such as:

```
<img src="reference">
```

when the web page was in the context of a web site, because of some wrong relative URL calculations.

See merge request !1153

Following up !941 , use a script ( $444 ) to rewrite most of XML.

The script was not so clever and skipped several cases that would be hard to implement.

'NoneType' object is not iterable

Since 05210e87 (erp5_web_renderjs_ui: add LabelField support,
2020-05-26) we have label field support, so this labelfield is no longer
rendered with the fallback "read only field" gadget and markup is
different. Update selector to make the test happy.

this is useful for an intermadiate dialog that does not require submit
button but still top 'cancel' link works.

Fixes test failure:

this report got broken in 2178cbed (pdm: fix pylint messages and
enable coding style test, 2020-03-09) there's no "Base" portal type.

This report has no test coverage, but the bigger problem is that the
graph from this report is not readable.

here as well we need to have body scripts after body for same reasons as
6b8e263b (monaco_editor: put body before head, 2020-06-01)

This fixes testDynamicClassGeneration failure since the migration of
IMovement (e8e5f273) which uncovered this issue.

ZODB Components: pylint: Generate astroid Module AST once for both the Component Module and its versioned Module.

This reverts commit 5b93b30f.

if such error occurs, this listfield show "You selected an item that was not in list" error message when save

- Add a Post interface so that we can use `Post` as a prefix for skins.

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.

Base_extractReferredObjectDictFromHtml except that base url to have a
leading /, because we ignore the first character of the normalized URL
returned by Base_normalizeUrlPathname.

By using / as base URL when we are in the context of the website, the
paths passed to Base_normalizeUrlPathname always start by / so we can
safely drop / from the normalized path returned by
Base_normalizeUrlPathname

because relative URL calculations in referenced pages extractions is
different when the page is in the context of a web site, we also have to
test this case

- compare references not uids
- set self.maxDiff=None to see full diff

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.
