Config system

[Zabuzard]

The bot should have a configuration file system instead of plain main arguments.

This would also greatly simplify the management of the two different bots (dev and master), by just giving them a different configuration setup (test-bot = true).

Initially, this config should contain the path to the DB, the bot token and a flag whether its the test-bot or not.

The community can decide on the data format for the config system, e.g.

• Properties 🎉
• JSON 🚀
• YAML 👀
• Other (name in comments)
