Add Russian emoji language

[step0ne]

I have problem with 'й' and 'Й'. Trying to fix by adding this cases to adapt_emoji_name, but some emoji don't process by this function. So i fix this inplace in data_dict.py by replacing "й" to "и".
Can u create new release with Russian?

I see the problem with Й. It happens because Й can be described in two ways in Unicode:
As a single unicode point: Й as \u0419
and as two unicode points: И + ̆ as \u0418\u0306

The ̆ symbol is not matched by regular expression class \w.

You can add the ̆ symbol to the regular expression here:
https://github.com/carpedm20/emoji/blob/master/emoji/core.py#L24
Just insert \u0306 after the existing \u0303

And then you can keep the й and Й and it should work.

I had fixed this problem. Thanks for comment😊
Could you make code review? And if it possible to make new version off library?

Looks good to me!

@TahirJalilov you can merge and release a new version
