Collective.dancing

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

- German translation has been updated.
[saily]

- Used i18ndude to find all untranslated msgid's. There were some updates in
collective.dancing queue-button-naming, so all guy's please help updating
collective.dancing's po files. [saily]

- Fixed a bug where when sending a preview we were incorrectly setting
the ``cue`` of the subscription that the preview is sent to. [nouri]

- Fix 264990: When sending out a newsletter from a content item
manually, we no longer assemble all message in the course of the
browser request. Instead, we schedule a job that's executed
asynchronously on ``tick_and_dispatch`` time. [nouri]

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

- Move file locking from queue dispatch to the ``tick_and_dispatch``
browser view. This is to make sure that we don't put duplicates
into the queue. This is because the underlying queue implementation
will actually work against us here by allowing simultaneous adds in
parallel ZODB- writes. [nouri]

- Fix 289779: Strip whitespace from e-mail addresses. [nouri]

- Added ``encoding`` attribute on the ``HTMLComposer`` class to make
it possible to either subclass and provide a different default
encoding, or set a persistent attribute. [malthe]

- Fix 280338: Images in header and footer text were sent with
relative URLs. [nouri]

- It's now possible to filter channels from the sendnewsletter view.
Simple by setting channel.sendable=False.
[tmog]

- Fixed an issue with installing collective.dancing from python.
The event-listener registering ISalt on creation of a new tool
no longer depends upon having a request. [tmog]

- zope.conf configuration with Virtual Host added in
documentation [macadames]

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

- Fix an issue where confirming pending subscriptions by visiting the "My
subscriptions" page. If a subscription is already confirmed the dictionary
``subscription.metadata`` does not have a key ``pending``. [saily]

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

- Rebuild ``collective.dancing.pot`` and updated German
translation. [saily]

- Removed bug in ``ManageSubscriptionsForm.remove``. When the search box
was added we also changed the ``ManageSubscriptionsForm.get_items`` method
to return the secret instead of the name. The remove method was not updated,
and delete of subscriptions did not work. [saily]

- Removed bug in CSV-export. Export must have same ordered fields or
columns as expected on import. As we are using the composer schema
for import, we should use this for export too. [saily]

- Make CSV export and import use the same delimiter.
[saily]

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

- Fix an issue where the scheduled send-out would send out items in
their short form, i.e. only title and description. [miziodel, nouri]

- Add a search box to the subscriptions administration view.

Prior versions of S&D didn't populate the subscribers fulltext index
correctly. This version adds an upgrade step that you'll need to
run in order to reindex all your subscription objects.

Refer to the Upgrade_ section for details on how to run upgrades.
[nouri]

- Allow pending subscriptions to be conformed by visiting the "My
subscriptions" page. This allows users to confirm their
subscriptions even if they've lost or never received their message
for confirm. [nouri]

- More fine-tuning of the ``PloneCallHTMLFormatter``: Strip unwanted
content like the review history in a configurable way. [nouri]

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

- Added workaround for a bug in the composer where ``header_text`` or
``footer_text`` are ``None``. No idea why they're ``None``, though.
