Adds ability to set any parameter to notification

[matt-pawley]

Adds a setParameter method to OneSignalMessage to allow the setting of any API parameter.

Example usage:

public function toOneSignal($notifiable)
{
        return OneSignalMessage::create()
            ->subject('Example')
            ->body('Example body')
            ->setParameter('ios_badgeType', 'Increase')
            ->setParameter('ios_badgeCount', 1);
}

Would fix #16

Any update on this?

@sald19 - I've no idea if this will ever be merged, if you want to use my fork, you can do so by updating your composer.json as follows:

 "repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/toughdeveloper/onesignal"
    }
],
"require": {
    "laravel-notification-channels/onesignal": "dev-master"
},

@toughdeveloper Thank you for your contribution! I will add Tests for this and then we could release the next version from this package.
