Define terminology

[m-rey]

I opened this issue, as the documentation and website use different terminology for the same thing. Furthermore some words are used for different concepts. Therefore, to clear things up, I'd like to gather and define the terms used so that I can edit the corresponding texts afterwards.

• messaging plattform / platform / platform account / bot account / bot / social network
• Kibicara instance / hood / hood system
• Kibicara instance / deployment of Kibicara on server
• hood subscriber / hood member
