Collective.dancing

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

- Fixed translations that were causing compile errors on Zope startup,
resulting in old translations showing up for a language (taken from
the outdated .mo file), or no translations at all.
[maurits]

- Updated Dutch translations.
[maurits]

- Fixed a bug that made it impossible to delete some subscriptions.
[regebro]

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

- Added a development buildout and automated test runner setup to the package.
[hannosch]

- Fixed ConfigurationError: ('Missing parameter:', 'description') on Plone 3
with the last upgrade steps.
[toutpt]

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

- Added missing upgrade steps for all recent versions. This makes the package
comply with the upgrade logic of the Plone add-ons control panel.
[hannosch]

- Follow best practice and decouple the profile metadata from the software
version in setup.py.
[hannosch]

- Added a z3c.autoinclude entry point to mark this as a Plone add-on.
[hannosch]

- Added our own overrides.zcml to load the one from plone.z3cform. You cannot
load overrides in the configure stage.
[hannosch]

- Add log on ATTopic Patch.
[toutpt]

- Update French translations.
[toutpt]

- Fix i18n pot file by escape quotes.
[toutpt]

- Extended the HTML composer so that you can select which composer template
to use. You register new composer templates by instantiating a template
somewhere in your code::

>>> mytemplate = ViewPageTemplateFile('browser/composer-html.pt')

and registering that in ZCML::

<utility component=".module.mytemplate"
name="My Custom Template"
provides="collective.dancing.interfaces.IHTMLComposerTemplate" />

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

- The attribute 'subscribeable' now defaults to False on newly created
channels. This means newly created channels will not show up on my-subscriptions
before they are made subscribeable from the channels configuration page.

- Disabled stoneagehtml style attributes blacklist since it stripped
out font-familiy from the styles added to a channel which confused
several users. This fixes http://tinyurl.com/ygmhv7a
Unfortunately its not possible to specify a custom
black list like stoneagehtml.compactify(html, filter_tags=['position'...])
since the stoneagehtml dosen't support that yet - http://tinyurl.com/ykwca4p.

- Fixed bug that caused the "Include collector items" option to
be ignored (i.e. always on) in "Send as newsletter" previews.
Also, there is now a default cue for the dummy preview subscriber.
The cue is always "one week ago".
[tmog]

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

- Changed the email address validation. The old one allowed a few bad
addresses to slip through - addresses with trailing dots for instance.
The new validation is generally stricter. Note that 'simple' local addresses
like 'adminlocalhost' are no longer allowed. For special use-cases where you
need this, you must change the validation RegExp. However, for most usecases, I
believe this is a big improvement.

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

- Added alternative "My subscriptions" page. It's based on a single form
with subforms, instead of multiple forms like the old one. It's main
feature is that it displays the ISubscriptionKey (the email address ;-))
and "subscribe" button only once. It has a checkbox for subscribing to
each channel.
To try the new version, select it from the new "Global settings" controlpanel.

- Translated new messageids for german language and updated some old ones.
