Implement Telegram Games platform.

[noplanman]

Finally add the Telegram Games platform!

WIP because it needs to be tested first ❗️

Closes #726

[noplanman]

Since nobody seems to have a game to test this, I think we just merge and wait for feedback from anybody who uses it down the line.

What do you guys think?

I'd like to test this but I guess I can't fetch it locally since I don't have the rights to do so?

Maybe you could indeed merge it and then let me update it to test it then?

[noplanman]

@SirDerpington You should be able to just fetch it from my branch, it's public.

Are you familiar with git? You can add my repo as a remote and then check out the branch:

$ git remote add noplanman https://github.com/noplanman/php-telegram-bot
$ git checkout noplanman/726-games

or if you've simply used composer to fetch the project, you could just fetch my branch directly.
Change your composer.json to use my repo and get the correct branch, then simply composer install it to get it 👍

        }
    ],
    "require": {
        "longman/telegram-bot": "dev-726-games"
    }
}

@SirDerpington Have you managed to do some testing on this?

[SirDerpington]

@noplanman Sorry, I've been working on something else the last two weeks. I think I can take a look at it next week.
It's stll on my todo list since we need that feature sooner or later!

[akalongman]

I think we should merge and after testing and user feedback we will improve this feature

[akalongman]

@noplanman please update your branch with current

@SirDerpington did you found time for testing this feature?
