Added discord project - WIP

[swixfort]

Hi,

I added a discord project to the solution using Discord.Net. When creating a bot for Discord it is now possible to use it there. It is a work in progress and maybe you want to check this out on stream whether it's a basis for a discord module.

There are a few things I already found out:

• Hangman is a bit buggy because "*" is a format character in discord and so it's not easy to see how many characters the word has
• I wasn't able to verify why there's sometimes a problem when connecting (hence the Delay in the constructor)

How to get the config: DiscordToken:

1. create an app
2. add a bot
3. create a link in OAuth2 via scope "bot" and your desired permissions
4. go to bot, get the token

ChannelID:

1. enable dev mode in discord
2. right click on desired channel
3. copy Id

Somehow I missed the other PR with discor. So I guess you can ignore this one and it was some lesson for me :-)
