Plone.app.content

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

- Reduce the required table item keys to ``id`` or ``getId``.
[elro]

- Make all columns other than title optional in table view.
[elro]

- It is the portal_type that is listed in `typesUseViewActionInListings`.
[elro]

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

- Preserve filename extension when picking a unique name.
[elro]

- Depend on ``Products.CMFPlone`` instead of ``Plone``.

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

- Avoid using a mutable default argument in the FolderContentsTable code. In a
LinguaPlone environment after viewing the folder contents of a collection,
the language of that collection got stuck as a content filter and wasn't
reset anymore. Viewing the folder contents of any item in a different
language showed an empty table until the Zope instance was restarted.

- Use the folder as the factory expression context when a front-page
is used as the display for the folder. Tests in `plone.app.contentmenu`.

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

- Update license to GPL version 2 only.

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

- Fetch the folder contents view icon more directly.

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

- Speed up folder contents view by only creating the necessary data for
items in the batch to be displayed.

- Disable KSS updates for "select all" and "show all items/batched" in
"folder contents" view as they are broken for folders with lots of content.
