Allow edition in the new UI

Ensure float/integer field can align right on the listbox
See nexedi/erp5@cfbc621b

When `Form.proxifyField` is used to make a proxy field from a field which has only a TALES and no value, it creates a proxy field with inconsistent internal data structures where `has_value` method does not work as expected. As a consequence, proxy fields to list fields are often broken in the ods/odt rendering.

Here is a scenario to reproduce the problem:

* add `Base_viewDummyFieldLibrary` ERP5 Form
* add a `LinesField`, with id `your_test_base_field`. Change `size` to 1 (not really required but I did this in screenshots here)
* add another `LinesField`, with id `your_test_field` and in this field:
   * set a `default` (`2`) in values, it's only needed to visualise the problem in ods style:
![set default and no items](/uploads/0cb9e229b0ca6761bb15f3d8845ea3f8/image.png)
   * set `items` in TALES (`python: [('one', '1'), ('two', '2')]`) , this will be the problem
![set items in TALES](/uploads/93d90f57e15afdcca60324675b59086a/image.png)
 * So far, when this is rendered as ODS, everything is fine:
![ODS before](/uploads/ce387cd7a5146585104470bf099f890b/image.png) 
this is also what we see in html style view: ![html before](/uploads/650330951ed286576f8366bbd5c44139/image.png)
 * use the proxify action, to make `your_test_field` be a proxy field to `your_test_base_field`
![proxify action](/uploads/9ff7b29141ce7f170f340c842fd76830/image.png)
 * result of proxify action looks good, both for values:
![values after proxify](/uploads/a9f7df3cd2d0af1e036aeff352624760/image.png) and for TALES:
![TALES after proxify](/uploads/aeaaa45cc9e91e9327781d85ec1efd57/image.png)
 * but after this rendering the form with ODS becomes broken:
![ODS after proxify](/uploads/d4e7be3251c596de35333526d4f6277a/image.png) even though it looks fine with html views.

`erp5_ods_style` knows how to render list fields and it uses the "display" (two) and not the "value" (2), this is done [here](https://lab.nexedi.com/nexedi/erp5/blob/451ce4137dc1d006bc2cd155535523d51a928150/bt5/erp5_ods_style/SkinTemplateItem/portal_skins/erp5_ods_style/field_ods_macro.zpt#L60) with a check depending on `field.has_value("items")`.

`has_value` is implemented like [this](https://lab.nexedi.com/nexedi/erp5/blob/451ce4137dc1d006bc2cd155535523d51a928150/product/ERP5Form/ProxyField.py#L598-611) for proxy fields:
```python
  def has_value(self, id):
    """
    Return true if the field defines such a value.
    """
    result = None
    if (id in self.widget.property_names) or \
       (not self.is_delegated(id)):
      result = ZMIField.has_value(self, id)
    else:
      proxy_field = self.getTemplateField()
      if proxy_field is not None:
        result = proxy_field.has_value(id)
    return result
```

and like [this](https://lab.nexedi.com/nexedi/erp5/blob/451ce4137dc1d006bc2cd155535523d51a928150/product/Formulator/Field.py#L80-86) for traditional fields:

```python
    def has_value(self, id):
        """Return true if the field defines such a value.
        """
        if self.values.has_key(id) or self.form.has_field(id):
            return 1
        else:
            return 0
```

when the value is defined on the proxy field and not delegated to template field, the condition is `self.values.has_key(id)`.

But `Form.proxifyField` when transforming a traditional field in a proxy field does not keep the `id` in `self.values` if it's only needed in `self.tales`. This is the root cause of this problem, if we inspect the field, it is something like this:

```
(Pdb) self
<ProxyField at /erp5/portal_skins/custom/Base_viewDummyFieldLibrary/your_test_field>
(Pdb) pp self.tales
{'field_id': '',
 'form_id': '',
 'items': <Products.Formulator.TALESField.TALESMethod object at 0x7ffa705c7450 oid 0x572626 in <Connection at 7ffa42c1a610>>}
(Pdb) pp self.values
{'default': '2',
 'field_id': 'your_test_base_field',
 'form_id': 'Base_viewDummyFieldLibrary',
 'title': 'Test Field'}
(Pdb) self.has_value('items')
0
(Pdb) 
```

If we edit the proxy field, it will repair itself, because the proxy field edit method maintain `self.tales` and `self.values` consistent, but this is not the case  with`Form.proxifyField`, which mutate directly `.tales` and `.values` and can make them have different keys - which is not supposed to happen.

The problem is that most of the proxy fields we have have been generated by `Form.proxifyField`, so for most of our fields the XML data of business template has this inconsistency. We could have took the easy way and make change `ProxyField.has_value` to understand this case, but it's probably better to fix the data. 
`erp5_hal_json` also uses `field.has_value` in some places, so it's better to fix at field level and not to address this in `erp5_ods_style` and `erp5_odt_style`.


These changes:
 - add a little more test coverage for `ProxyField.has_value` ( at first I thought the problem was only in `has_value`)
 - Fix `Form.proxifyField`
 - add a `ProxyField.checkConsistency` to check that `.values` and `.tales` are in sync - or more exactly that all entries from `.tales` are also in `.values`, because this is what cause the problem with `has_value`.
 - re-export all proxy fields after cleaning up their `.values` and `.tales`, using `checkConsistency(fixit=True)` on all proxy fields.

Try to support displaying web js site from google cache,
which can not access original gadget, due to cross origin ajax query forbidden.

Display original content instead and load the default CSS in such case.

Most ERP5 web sites use a global form wrapping the content.
Modify the html viewer to not drop this content.

Stop using ck_editor in read_only to display HTML.

This allows to get rid of the ck_editor iframe, allowing a faster load and removing the iframe scroll.
The maximise button is no more needed in such case.

It also removes all ck_editor links handling: links can be open in another browser tab now.

This changes impacts both xhtml style and erp5js.

This gadget take an HTML string as parameter.

It first cleans it up (with hardcoded behaviour currently) by dropping unknown tag elements, unknown/unsafe tag attributes.
It is another protection layer on top of asStrippedHTML inside ERP5.

Then, it displays the output HTML and style it with an hardcoded set of rules.
