Discord Bot setup + custom Event/SlashCommand handler

The package (initHandler) allows to organize command and event modules under different folders that describe separate systems
rather than putting every module inside single "commands" and "events" folders, which can make it hard to edit specific systems (in the case of a multifunctional bot)

It also uses `.env` module to keep the sensitive info protected from getting leaked on GitHub (with .gitignore file) 

Hierarchy example (in src folder):
    systems (folder)

        levelling (folder)
            commands (folder)
                getExp (file)
            events (folder)
                messageCreate (folder)
                    giveExp (file)

        welcomeMessage (folder)
            commands (folder)
                configure-channel (file)
                remove-channel (file)
            events (folder)
                memberAdded (folder)
                    printWelcomeMessage (file)
