Add django queryset lookup like field selection

AuthorPermissionLogic and CollaboratorsPermissionLogic now understand
the django queryset lookup type field specification. Thus the following
code works as exepcted if the Project model have `author` and
`collaborators` field and Article model have `project` field.

    author_permission_logic = AuthorPermissionLogic(
        field_name='project__author',
    )
    collaborators_permission_logic = CollaboratorsPermissionLogic(
        field_name='project__collaborators',
    )

If your custom permission logic require this lookup, import
`permission.utils.field_lookup.field_lookup` and use as:

    from permission.utils.field_lookup import field_lookup

    # fetch object instance by field_lookup
    author = field_lookup(article, 'project__author')
    # you can specify the lookup as many as you want
    collaborators = field_lookup(university,
        'semesters__lectures__collaborators')
