Adds documentation for object syntax.

Updates the docs regarding the object syntax.
I don't think the hash needs to be separate. I think we should also note that you can pass in a context for all of them.
```js 
// Connect all of the commands at once.
myChannel.comply({
  'some:command': this.myCallback,
  'some:other:command': this.someOtherCallback
}, this);
```
