Imio.helpers

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

- Added method to safe encode string.
[sgeulette]
- appy.pod usecase : table using width of 0px.
[gbastien]
- In `content.validate_fields`, added special bypass to avoid failing
validation for `Choice` field that is `required=False` and for which given
value is None. Validation fails because None not in vocabulary but it is
nevertheless a correct value as it is managed by the widget while added thru
the UI.
[gbastien]
- Added JS fix to be able to print `<fieldset>` on several pages in Firefox,
see https://bugzilla.mozilla.org/show_bug.cgi?id=471015.
This makes it necessary to add a default profile to add the JS resource
`++resource++imio.helpers/helpers.js`.
