display a confirmation page before deleting pages
Added support for setting custom django permissions in content types

Currently FeinCMS ignores custom permissions which are set in content type
models.
So, for example, this code will not work as expected (defined permissions are
ignored):

    class SomeCustomContent(models.Model):
        ...
        class Meta:
            abstract = True
            permissions = (
                ("view_task", "Can see available tasks"),
                ("change_task_status", "Can change the status of tasks"),
                ("close_task", "Can remove a task"),
            )


This change adds support for custom permissions in content type models.
css hacks for django-suit compatibility
Trigger djangos inline deletion handler when removing an unsaved content. Poorify all other contents before, and richify them afterwards to keep the richtext editors working.
