Add Acknowledge function to ApplicationCommandInteractionCreate for HTTP server interactions

[BowsiePup]

This pull request introduces a new function to ApplicationCommandInteractionCreate

ApplicationCommandInteractionCreate.Acknowledge()

Additions:

New Interaction Response Type:

InteractionResponseTypeAcknowledge. A Strictly internal iota to identify this response type.

New function:

ApplicationCommandInteractionCreate.Acknowledge(). This method is used to respond to the original HTTP request from discord with StatusAccepted (202).
This is not like ApplicationCommandInteractionCreate.DeferCreateMessage(). You are still required to respond with a new HTTP request within 3 seconds to respond to the interaction.
Unlike ApplicationCommandInteractionCreate.CreateMessage(), you are able to access the response which will contain error or the sent message when you send event.Client().Rest().CreateInteractionResponse()

Source to this can be found here
If you send this request for an interaction received over HTTP, respond to the original HTTP request with a 202 and no body.

This is the preferred way to respond to Interactions as you can receive the message created in the response if u need it and errors.

Looks like a good addition. Can you also add the Acknowledge method to the other interaction events?

All requested changes have been added.

Autocomplete does not as it does not have a Interaction Callback Type and you are expected to respond via the http response on the original request.

A few issues fixed:

Auto complete does have an interaction type: APPLICATION_COMMAND_AUTOCOMPLETE_RESULT 8
Added the function to AutocompleteInteractionCreate

Moved InteractionResponseTypeAcknowledge out of the iota const as it broke the iota making all items be one extra then they should be. I moved it out to keep the iota + 1 so it still matches with discord docs.
