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>

erp5_web_renderjs_ui: keep previous focus color

This reverts commit a87db49b.

for security reasons, info on users, or existence of usernames shouldn't be leaked from the system.

manage_FTPget is an API to serve the file content to response, it is not
suitable to just get the file/page template content like we need here.
It was causing issues when running through activities, because timerserver
responses does not have the setBase method, but is also wrong because
large files are streamed to response directly.

Zope does not really offer an unified API to get the source of page
templates or files, except the PrincipiaSearchSource method which it uses
for its builtin search engine. It seems suitable to use here as well.

Also add a test for the case where web pages are in a OFS.File, only
the case of PageTemplate was covered.

Use the `ui-list-grid` class on a `ul` element.

```
return gadget.getTranslationDict([Foo])
  .push(function (translation_dict) {
    console.log(translation_dict['Foo'])
  });
```

```
return gadget.getCommandUrlForDict({
  foo_key: {
    command: 'display'
  }
})
  .push(function (url_dict) {
    console.log(url_dict.foo_key);
  });
```

erp5_web_renderjs_ui_test: Add page to be used as example of links to extra menu and cover it with test

The query planner does not seem to notice that we are trying to know if
any row exists matching a set of dependency values, and it keeps scanning
multiple row for each value - which is unproductive.
So split dependency queries from (pseudo-code)
  WHERE <column{,s}> IN <values{, pairs}>
to unions of
  WHERE <column{,s}> = <value{, pair}> LIMIT 1
which produces query plans which do stop immediately when finding a
candidate row.
On a serialization_tag query with 40 values and real-world indexations,
this reduces the number of rows scanned by mariadb from 500 (<10%
efficiency) to 40 (100% efficiency).
The produced SQL is significantly larger (~3x, around 500kB on
real-world sample data, but may vary a lot depending on value length),
but if this has any effect is is more than compensated by the improved
query plan efficiency.

For test components, we don't use getBusinessTemplateList but define the
business templates to be installed as (test) dependencies of the business
template containing the test.

update test after c3eb0b30 , because non editable editor now render HTML
