Adds getApplicationCommands() methods to Swiftcord and Guild, to return an array of ApplicationCommand objects which can be inspected. ApplicationCommand objects aren't meant to be used to make new commands, just see what's currently in the global and guild spaces for a bot.

Also add a parameter to request() and requestWithBodyAsData() and their associated baseRequest...() methods to tell them to return the JSON received from the API as the Data, rather than running it through JSONSerialization and turning it into objects. This is useful for callers who want to just use the straight JSON data to use JSONDecoder to build objects.

Make init methods throwable for ApplicationCommand and other objects it uses, so we can check for property length/size requirements, thus avoiding "Invalid Form Body" errors coming back from the API in these situations. Some other changes regarding Codable conformance of property names (snake-case vs. camel-case).

This new privileged messageContent intent is now required for receiving full content of all messages. Without this, as of September 2022, a bot will receive content of messages only in specific circumstances, such as when you @mention the bot.

For example, without this, if you just write "Hello everybody!" in a guild, a bot will still receive the event with some related info in it, but the event won't contain "Hello everybody!" anywhere in it since this intent is not enabled.

Added an addChoices() function to ApplicationCommandOptions that takes a pre-built array of ApplicationChoices, in addition to the variadic form. Added addRole() and removeRole() to Guild to implement those endpoints in the API.

This allows the extension to mutate without needing mutating, allowing calling deferReply and setEpheremal from a ListenerAdapter, which receives classes by reference and not by inout (required to call mutating funcs).

In short, you can now call deferReply and setEpheremal on arguments in ListenerAdapter as the examples show.

This PR fixes some eventloop lifecycle issues as well as adding a case for the websocket errorcode normal closure

Without the handling of that error code, discord would send the code and the bot would stop as discord said it wasn't needed anymore. Now however we try to reconnect on an incoming normal closure request

We need the guilds intent for caching. If the user doesn't include this intent, many functions are rendered useless. As such we will force the intent.

I wouldn't have made this PR, but it is very important. So I didn't realize that url.path didn't include the params needed to connect to the proper API version. As such, it was actually on gateway v6. This PR fixes it and uses EmbedBuilder for sending embeds.

This adds Slash Commands, User Commands, Message Commands, Button and Select Menus, Threads, Guild Scheduled Events, Stage channels and a more in depth Activities setup.

• Adds a notice because .package(url: String, requirement: Package.Dependency.Requirement) is deprecated in swift 5.5 and up
• Fixes the code in the onMessageCreate function so that it now compiles
• The main class example now uses 4 spaces for indention, to be more consistent with the Package.swift example

Adds subcommand support for slash command To produce a clearer way to handle the subcommand type of option, a refactor to SlashCommandEvent might be needed.

This PR adds voice support to Swiftcord.

What works

• Playing PCM and Opus Audio
• Basic Gateway support

Todo

• Handle Voice Gateway errors
• Try to add ffmpeg support (I have had insane trouble with it taking too long)
• Receiving audio
