The `Command` and `EventListener` constructors both take an optional object argument containing additional options. #98 introduced new forms for these constructors, which place the options argument before the function argument, and deprecated the old forms which place the options argument at the end of the argument list.

Deprecated forms can be replaced by simply switching the position of the arguments, like so:

```js
// old
new Command('test', message => {
  // ...
}, {
  guildOnly: true,
  permissions: ['manageMessages'],
})
new EventListener('ready', () => {
  // ...
}, {once: true})

// new
new Command('test', {
  guildOnly: true,
  permissions: ['manageMessages'],
}, message => {
  // ...
})
new EventListener('ready', {once: true}, () => {
  // ...
})
```

Omitting the object argument entirely is still supported:

```js
new Command('ping', message => {
  // ...
})
new EventListener('messageCreate', message => {
  // ...
})
```

The object-last constructor signatures of `Command` and `EventListener` will be removed in the 3.0.0 release.
