i18n doesn't handle node.title correctly; contents, topic, admonition, table and section

Original report is: https://groups.google.com/d/msg/sphinx-users/hdzuCi7AvRY/etw-3qWBBAAJ

Problem

There are two problems

1. make gettext doesn't generate msgid for title of topic directive and contents directive

ex.

.. contents:: Contents Title

.. topic:: Topic Title

2. make html with i18n catalog doesn't apply translated message if msgid starts with 1.

ex. index.rst

1. A Header
===========

.. admonition:: 1. Admonition Title

   Admonition body

.. topic:: 1. Topic Title

   Topic body

.. contents:: 1. Contents Title

.. table:: 1. Table Title

   +---+
   |Foo|
   +---+

Procedure to reproduce the problem

locale_dirs = ['./locale']
language = 'ru'

commands:
