Fix Lua code highlighting

A rather blunt fix that offers a temporary workaround.
The reason behind original Lua lexer not highlighting Lua code is '!' used as
delimiter. Pygments fails to parse '!' as a Lua code entity and tells Sphinx to
leave the code unhighlighted. The fix adds custom Lua lexer by alias 'lua_tarantool',
with '!' added as a punctuation token (line 60 in LuaLexer.py). A proper fix would
probably be to extend the lexer with all Tarantool extensions over standard Lua modules.
Lua code block directive now should be used like this:

.. code-block:: lua_tarantool

	lua code
