Imio.helpers

-----------------

- In `xhtml.storeImagesLocally`, do not break when a `resolveuid` is found but
it does not find the image. This can be the case when copy/pasting HTML code
from another instance or so.
[gbastien]
- In `xhtml.removeBlanks`, check if content is empty by calling
`xhtml.xhtmlContentIsEmpty` with parameter `tagWithAttributeIsNotEmpty=False`
so empty tags with attributes are considered empty.

[gbastien]

-----------------

- Added collapsible option on container view.
[sgeulette]

in a volatile (_v_...) as it seems "stored" by thread and is computed to much
times.

`<td>` has a defined size.

`<tr></tr>` that do not render second column of following lines.
[gbastien]

[gbastien]

-----------------

- Display more logging in `content.validate_fields` when bypassing validation.
[gbastien]
- In `catalog.addOrUpdateIndexes`, pass a `ZLogHandler` to `reindexIndex` so the
progress is shown in the Zope log.
[gbastien]
- In `content.add_to_annotation` and `content.del_from_annotation`, store
annotation in a `PersistentList` instead a `set()` to avoid persistence
problems.
