[Feature] add 'HandlerTypeCallbackQueryGameShortName'

[oanhnn]

Problem

A handler with type HandlerTypeCallbackQueryData will be matched by update.CallbackQuery.Data.
So, you MUST use RegisterHandlerMatchFunc to add a handler for CallbackQuery with game_short_name (the data field may be empty. See more https://core.telegram.org/bots/api#callbackquery).

This feature will help you add a handler for CallbackQuery with game_short_name more easily.

Solution

Add const HandlerTypeCallbackQueryGameShortName.
A handler with type HandlerTypeCallbackQueryGameShortName will be matched by update.CallbackQuery.GameShortName.
