Plone-app-iterate

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

- Added profiles/default/metadata.xml (version 120: lets leave plenty room in
case any profile changes are needed on the 1.1 branch).
[maurits]

- Avoid a test dependency on quick installer.
[hannosch]

- Use our own PloneMessageFactory. We don't depend on CMFPlone anymore.
[hannosch]

- Specified package dependencies.

- Made the tests independent of default content.

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

IReferenceable. This fixes http://dev.plone.org/plone/ticket/8737

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

- Fix action conditions for the nth time; this time it's an
over-ambitious "Cancel check-out" permission. This fixes
http://dev.plone.org/plone/ticket/8735
[nouri]

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

- Refine permissions fix from 1.2.0 and make tests pass again:

Don't require Modify Portal Content (MPC) permission on the
original to check out, which was omitted in the fix for 1.2.0.

Don't require MPC on the original for canceling of checkout, only
require it on the working copy.

- Fix missing internationalization (8608 thanks to Vincent Fretin)
[encolpe]

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

- Allow users without modify content permissions (but with the iterate
check out permission) to check out items, and only allow them to
check in back again only when they have modify content permissions.
