Add support to gateway intents

[SrGaabriel]

When i disable those few intents:

    private val disabledIntents: List<GatewayIntent> = listOf(
            GatewayIntent.DIRECT_MESSAGE_TYPING,
            GatewayIntent.DIRECT_MESSAGE_REACTIONS,
            GatewayIntent.DIRECT_MESSAGES,
            GatewayIntent.GUILD_MESSAGE_TYPING,
    )

This runtime error shows up:

Your code has nothing to do with your exception. I'm running bots that only use a single intent GUILD_MESSAGES and they work fine.

[MinnDevelopment]

I assume you enabled a privileged intent which caused your bot to shutdown immediately. This would then cause the ReactiveEventManager to also shutdown, causing this exception.

If that is the case, then this is an issue with your setup and not with this library.

I recommend you read these:

• Gateway Intents and Member Cache Policy
• I'm getting CloseCode(4014 / Disallowed intents...)-Troubleshooting#im-getting-closecode4014--disallowed-intents)

[MinnDevelopment]

Closing this, there is nothing this library needs to do in order to support intents.

Uhm, ok thank you for the support and sorry for the inconvenience!
