Do not access form submission REQUEST from the listbox list method,
as it is rendered asynchronously in ERP5JS

This reverts commit 35b2c024.

Allow edition in the new UI

This make everything slow as hell and prevent to quickly save.

Example: <h2 class="foo">bar</h2> => <h3 class="foo">bar</h3>

Changing the language and browsing to another web section require to fully refresh the page.

This breaks the previous gadget API.

The default value of the field was calling Base_getEditorFieldPreferredTextEditor and returned the preferred text editor, because this script assumes the content type to be text/html by default

Ever since the introduction of X-Balancer-Current-Server in SlapOS
haproxy configuration in:

      erp5_cluster: leave ERP5 set the haproxy cookie

the balancer will overwrite this cookie's value, so do not compare it
to our name: balancer may be calling us a name completely unrelated to
the value getCurrentNode returns.
So simplify this function's logic to only do what the docstring says:
decide when to set and when to unset the balancer cookie, and let the
balancer decide the value.
This resolves cases where Zope would set the cookie over and over on
every request when getCurrentNode and balancer disagree on its value.

- use environment variables to pass SLAPOS_TEST_LOG_DIRECTORY and SLAPOS_TEST_SHARED_PART_LIST, as discussed on nexedi/nxdtest!2
- Fix #20200514-218C705 - [testnode] frontend for log access

See merge request nexedi/erp5!1304

This is used and should not be disabled.

There was an error when clicking this dialog, fix that error instead.

See merge request nexedi/erp5!1301

In ERP5JS when redirecting we can use `portal_status_level` to control the appearance of the notification.

This updates the cases when user action could not be performed to redirect with an error level, so that notification appears in orange, not in green (in ERP5JS - in erp5_xhtml_style this has no effect).

accounting, base, trade were updated

so that installed objects are owned by System Processes and we can have faster ownership checking for proxy role scripts.

Portal is the Skinnable object, skin magic belongs there.

Also, modernise it a bit.

testnode use to publish the URL of logs so that Nexedi ERP5 can
display link to "view logs". This URL was an IPv6 URL on a certificate
which does not validate.

Now testnode software release request a shared frontend for these
logs and generate a config file with log_frontend_url set.

testnode now advertise the URL of log using the log frontend url
from config.

Also simplify frontend_url key to manage it using the same way.

SLAPOS_TEST_LOG_DIRECTORY and SLAPOS_TEST_SHARED_PART_LIST have been
introduced recently, they are passed to runTestSuite using the usual
way of running runTestSuite once with --help to inspect supported
arguments and passing the argument only if runTestSuite supports them,
but these arguments are not necessarily heavy to compute and are always
known (unlike for example firefox path which is only known if seleniumrunner
extra software was installed), so simplify all this by passing the
parameters are environment variables.
