Pytgbot

- Fixed failed version bump, which causing importing this package impossible.

- This is **not** Telegram `Bot API 2.3.1`!
- This version doesn't work. Use `2.3.2` instead.
- Fixed InlineQueryResultCachedSticker.

- Updated API changes of [`Bot API 2.3` (November 21, 2016)](https://core.telegram.org/bots/api-changelog#november-21-2016)

Changes I observed:
> Bot
>> **`answer_callback_query`**: added `cache_time`
>> **`edit_message_text`**: works for game messages too.
>> **`set_game_score`**: added `force`
>> **`set_game_score`**: added `disable_edit_message`
>> **`set_game_score`**: removed `edit_message`
>> **`set_game_score`**: `score` can be `0`. Now must be non-negative, before it must be postive.
