✨ Implement an optional react/http server (Fixes #21)

[Log1x]

This is an initial HTTP server implementation for react/http with full Laravel routing support. This will allow you to create webhooks and an API to interact with your bot.

Remaining Changes

• Extract into an override-able Kernel.
• Add sane default middleware (ConvertEmptyStringsToNull, TrimStrings, rate limiting, etc.)
• Add API token support (bot:token generator command, default auth middleware, etc.)
• Implement support for Controllers and make:controller for complex routes.
• Decide on final directory structure when used in Laracord.

Testing

If you would like to help test this PR as-is, you can try it out with the following:

composer create-project laracord/laracord
cd laracord
composer require laracord/framework:dev-feat/21

app/Bot.php

<?php

namespace App;

use Illuminate\Support\Facades\Route;
use Laracord\Laracord;

class Bot extends Laracord
{
    /**
     * The HTTP routes.
     */
    public function routes(): void
    {
        Route::get('/', fn () => collect(Route::getRoutes()->getRoutes())->map(fn ($route) => $route->uri));

        Route::get('/commands', fn () => collect($this->registeredCommands)->map(fn ($command) => [
            'signature' => $command->getSignature(),
            'description' => $command->getDescription(),
        ]));

        Route::get('/servers', fn () => $this->discord()->guilds->map(fn ($server) => [
            'id' => $server->id,
            'name' => $server->name,
        ]));

        Route::get('/channels/{server}', fn ($server) => $this->discord()->guilds->get('id', $server)?->channels->map(fn ($channel) => [
            'id' => $channel->id,
            'name' => $channel->name,
        ]) ?? ['message' => 'Server not found.']);

        Route::get('/message', function () {
            $this
                ->message('This is a message from the HTTP server.')
                ->title('Hello from HTTP land!')
                ->send('your-channel-id');

            return ['message' => 'Message sent!'];
        });
    }
}

Once you boot your bot, it will be accessible at localhost:8080 by default.

Out of the box, it also includes the Symfony error handler when in local/development:
