Plone.app.linkintegrity

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

- unicode links should not raise errors. Fixes https://dev.plone.org/ticket/13468
[vangheem]

- Dexterity: use zope.lifecycleevent instead of zope.app.container
interfaces for Plone 4.3 support.
[jone]

- Avoid a bug during link integrity check when a source or target of the
reference has been already removed during the deletion process.
This can happen during large delete processes.

- Monkey patch the Zope HTTPResponse status_code to include a mapping for
linkintegritynotificationexception, to return a 200 code.

------------------
- Fix a remove confirmation view bug.
Displays the portal type title rather than the portal type name.
This change also broke some tests that were checking for the name
rather than the title, but I just fixed those.

- Added support for Dexterity content types. Link integrity
support for Dexterity requires the plone.app.referenceablebehavior
behavior to be enabled so that the Dexterity item can be used
with Archetypes references.

which prevented references from being created based on those links.

- Stabilize the sort order of breach sources returned for the
confirmation view.

- Use the `get` method to retrieve the field value if the instance
does not provide an accessor method. This is the case for instance
for fields which have been added via schema extension.

- Support resolveuid/UID references explicitly, by parsing and resolving
these ourselves instead of relying on a view or script (which doesn't work).
This fixes linkintegrity for sites with link-by-uid turned on.
This closes https://dev.plone.org/ticket/12104

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

[gotcha]

- Provide Archetypes-only fallback if `plone.uuid` is not available,
restoring compatibility with Plone 4.0.x.
