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.

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.

Some pointers for type scripts definitions:

In the previous approach, several "useless" request were still made
during edition.

https://microsoft.github.io/monaco-editor/ as an ERP5 source code editor

this commit is only a build of the vendor code.

It was built using https://lab.nexedi.com/jerome/monaco-editor-erp5/ at
revision b1ecc18f and uploaded to ERP5 following this procedure:

First enable webdav by adding in zope conf:
```
<webdav-source-server>
  address 127.0.0.1:12200
  force-connection-close off
</webdav-source-server>
```

This was built and uploaded to ERP5 with:
```bash
git clone https://lab.nexedi.com/jerome/monaco-editor-erp5.git/
cd monaco-editor-erp5
npm
npm run build
lftp http://login:pwd@127.0.0.1:12200/erp5/portal_skins/erp5_monaco_editor/monaco-editor/ -e 'mput dist/*'
```

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.

OfficeJS's user blocking third party cookie will at least stop entering their credentials many times for nothing

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.
