Just set indentation rules for now

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.

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 9d7f8b5 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/*'
```

This was not really backward compatible with old slapos versions not passing
zserver_address_list

To answer question in the comment:
> How to inspect inside another iframe?

use selectFrame (after waiting for the frame to be added in the DOM of course).

Reference of selenium commands: https://web.archive.org/web/20160807232621/http://release.seleniumhq.org/selenium-core/1.0.1/reference.html#selectFrame (I'm not sure it's still on the web)

Tests asserts that size have all languages available, so let's be
compatible and just set the default language to the current selected
one at site creation.

This was not really backward compatible when running with old slapos,
because default value was not string in this case.

This step was in reality only removing the "Access Content Information" permission for Anonymous on web_site_module, which was not coherent with erp5_web, and had for consequence to make developers change it by hand when wanting to use web_site_module

Extend test runners to use partition IP  and run functional tests behind an https frontend.

See nexedi/slapos!374 for the slapos part and more detailed explanations.

I made a mistake rebasing & applying the patch to master, so the test
added in
nexedi/erp5!726 (comment 65067) did not
reach master.

This reapplies this part.

Thanks Seb for noticing !

On the traditional editor (from portal_component), selected text was not
highlighted

This is something the webmaster will define.
Also, initialize available languages like this will select a random
default language, which the webmaster might not understand.

So that a declaration like:
context.getUrlFor({command: 'display_action', options: {jio_key: "document", page: "action_reference"}})
can return the URL to redirect to the given action or the document

As it is backward compatible, this option can be passed as environment
variable.

Also re-order all argument output to make it clear which comes from
SlapOS generated wrapper and which are passed by test node.

We now access zserver behind the backend apache on https:// and this
apache's certificate is not trusted

Otherwise running in debug mode on headless machines just display
cryptic error message.
