Make stock browser a dialog where user can select the node category, for compatibility with ERP5JS

Introduce a preference to select the node category by default.

Allow to select quantity unit / metric type in the dialog to get converted inventories.

This version allow sorting and fixes an XSS vulnerability

Browsers (at least chrome) saves the textarea content and restore it
when going back or resurecting a closed tab, which prevents loosing
unsaved work.
This browser feature does not work in "rich" javascript
editors, but this trick of syncronizing the rich editor content to a
hidden textarea seem to makes it work.

This is an emergency commit to repair failing tests

use "Slideshow" for now. "Slide Show" would also be OK, the discussion
about what's the best term is still ongoing, this is an emergency commit
to repair tests.

this has been merged in erp5_officejs

This gadget only works in ERP5JS, as it depends on multiple ERP5JS only gadgets.

Some functionnalities have not been backported for now:
* image upload, which seems broken on xhtml style
* test template (I was not able to trigger something from the UI)

Normally, it could be possible to create an OfficeJS app with this editor.

This functionality is enabled only if 'trusted-proxies' configuration
value is ('0.0.0.0',) by putting the following in zope.conf :

trusted-proxy 0.0.0.0

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

Convert the amounts in inventory list view, the movement history list
views still show in movement unit for simplicity.

At the same time:
 - don't cast to int() in macro, but expect caller to pass already
   correctly formatted values for *_inventory
 - document macro like it was done for erp5_pdm_ui_test

This was never counting movement, but the number of inventory brain that
the getInventoryList should return.
Document this macro and rename argument everywhere.

init macro cannot open the stock browser report, because some other
tests are assuming that this macro remain in view mode and they can
select another view.
move the "select stock browser report" in a stock-browser-test specific
macro

make the node_category dialog pre-select the preferred node category

Previously, these tests were displaying the listbox with two lines, one
for source one for destination and where checking both lines at once.
Now that it's possible to filter by node category (site) in renderjs as
well, adjust the test to select the node categories one by one and check
that the results for each line category is what we expect.

Also fix a few typos

This allows to filter the node by site in new and old interface in
a consistent way.

The domain tree is also removed for consistency (so that we don't have
different features on new and old interface)

Old UI tests have also been updated to use more meaningful macro names.

Having this as a dialog will make it possible for user to supply some
parameters.
In the old UI, this was relying on domain tree to let the user select
the sites they want to see, but in ERP5JS domain trees only work on
list mode listboxes.
Also, we have plans to make this browser more interactive, to let the
user choose more parameters (section category, quantity unit for
conversions etc) in the report dialog, but this was not possible in a
view action.

same as group

this will be used in stock report dialogs by site

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 nexedi/erp5!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

See merge request nexedi/erp5!1149

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 nexedi/erp5!1153

Following up nexedi/erp5!941 , use a script ( nexedi/erp5$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.
