Add more flexibility in the quote channel naming

[LouvAndTech]

Issue

For now there is a limited amount of personalization allowed regarding the name that the quote channel needs to respect for the bot to work.

Objectives :

• Add more name allowed as default quote channel
• Add a way for admins to avoid naming contraints (still without saving anything in the server's memory)

There is a possibility of encoding configs in a channel topic using json blob or clear json.
