Imio.helpers

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

to the CONTENT_TAGS (<p>, <strong>, ...) of a given xhtmlContent.
[gbastien]
- Add volatile_cache_without_parameters and
volatile_cache_with_parameters decorators
[mpeeters]

[mpeeters]

- Added case in 'appy_pod_sample' to check when style attribute is used to
define italic/bold/underline/strike directly on <li> or on <li> containing
<p> or <span>.
[gbastien]

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

- Added 'path' module with method 'path_to_package' that will return the absolute
FS path to a given package. An extra 'filepart' can be provided to complete the
returned path. This is useful to get a template in a 'browser/template' folder
for example.

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

- Do not pretty_print HTML returned by lxml.html.tostring or it can leads to
weird behaviors like extra blank space in case we have nested <span> tags.
'pretty_print' is now a parameter to relevant methods and is False by default
[gbastien]
- Added methods to create content from a dictionary, to get object following
criterias, to apply multiple transitions, to create a RichTextValue object
[sgeulette]
- Added default views for Dexterity content and container that display
fields in a table with widget label and the left and widget value on
the right. The view for container also includes an asynchronous
folder_listing that lists contained elements.
Taken from imio.project.core

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

- Use by default scale=2 instead of scale=4 when generating barcode.
[gbastien]
- Added methods int2word, wordizeDate and formatDate aiming to transform
numbers into french translation, date with only numbers into date in full
and to format dates (with hours, with month name in full, ...).
[DieKatze]

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

- Added constant CLASS_TO_LAST_CHILDREN_NUMBER_OF_CHARS_DEFAULT to define the
default number of characters to take into account while marking last tags
in xhtml.addClassToLastChildren. This way it can be used in other packages.
[gbastien]
- Fixed xhtml.imagesToPath to handle image src using 'resolveuid' correctly.
[gbastien]

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

- Bugfix in xhtml.storeExternalImagesLocally if downloaded external image has
no 'Content-Disposition' header.
