region/europe/western_europe is also present in erp5_tiosafe_test, which is
already installed in the same unit test. So add a dependency on that BT and
remove the duplication.

currency_module/euro is also present in erp5_tiosafe_test, which is already

Especially in chrome (75), it's very hard to see selected text in erp5
xhtml style interface, especially in listboxs.
Chrome adds a background color to selected text, but this background is
almost same color as ERP5 background.

This uses https://developer.mozilla.org/en-US/docs/Web/CSS/::selection
to make it visually clear what is selected.

Simplifies activity spawning when dependencies are conditionally set:
  activate(
    after_tag=some_value if some_condition else None,
  )
instead of having to do a ** dance.
All columns involved in dependency checking are declared NOT NULL, so providing
"None" and expecting a dependency to happen was already not working.
This change pushes this one step further by allowing activity
auto-validation also happen on these activities.
Also, simplify getOrderValidationText: avoid iterating on keys and then
retrieving values, use a list-comprehension, simplify condition.
Add a test for after_tag, also covering activity auto-validation.

Unit Tests: login*() with a non-ERP5TypeTestCase user was adding ERP5TypeTestCase user anyway and failure was silently ignored.

checkValidity calls getContent, which uses the same mutex

Improve the query speed by using the default listbox sort.

In ERP5 software release we now have `mock` egg installed, so we can use it in tests instead of doing manually like this:

```python
saved_method = Class.method
def patched_method():
  ...
try:
   Class.method = patched_method
   ...
finally:
   Class.method = saved_method
```

Change the caching policy to one hour.

Use the CDN to publish the page if the backend is down

Cache the manifest like the HTML page but force refreshing the manifest to prevent CDN cache inconsistency.

Defining it inside portal_components ledds to business template update issue.
Bypass it by defining the expected behaviour into the web section hook.

Allow the CDN to cache the content.

Use stale_if_error to allow the CDN to return content if backend is down

Unify Vary Header.

erp5_banking_cash depends from erp5_trade via erp5_banking_core.

Gadgets:

* Support `changed` flag from `erp5.js`: 

![unsaved changes sreenshot](/uploads/cff30eae0a5d87df26bac13d43e1da3f/image.png)

* Comply with translation protocol used in ERP5JS. This does not translate, because it would not be easy ( ERP5JS translate client side with a json database of message, but in xhtml style the translation is performed server side with localizer) and not so important now. What matters is just that we can somehow reuse gadgets.

Style:

* While we are at it, fix a minor annoyance that the button in "long" dialogs where not easy to reach, at least on chrome

Remove all globals to allow multiple live tests running on the same page.
Stop reading the test output if the browser tab doesn't have the focus.
Stop hardcoding the URL in the javascript.
Stop hardcoding other fields path in the javascript (+ embed the textarea in the gadget).

Propagate all parameters via formulator.
It will allow to use this gadget from another context document.

Run live test from the RJS UI

This way we can use gadgets using of ERP5JS translation API in xhtml
style.
This is really minimal compatibility layer and translation is not
actually performed.

Because typescript is a subset of javascript, running typescript
compiler on javascript files can already report several issues.

This is triggered by using "Format document" from context menu.

because gadget_editor.js was changed

So that we can edit web pages & web scripts with monaco

So that javascript editor provides hints for code using these libraries.
