gerbot - new charts and invite link

Yesterday I updated my discord bot with new commands:

^buyers token
^sellers token

gerbot will return simple charts like that one above with top sellers or buyers in last ~24h. Charts are generated from realized trades.
That way you can easily check who's buying or selling your token, without scrolling through block explorer.

From now you can also ask bot for a list of commands using ^help:

You can play with bot on steemleo discord:

Few people asked about the invite link for gerbot. I made some changes, cleaned code, restricted some commands to particular servers, and now I can share invite link with you:

have fun :)
