maknz/slack doesn't support Laravel 5.4

[Mopster]

Looks like maknz/slack doesn't support Laravel 5.4 and is no longer actively maintained. Checking the repository, the author added Note: this package is no longer being actively maintained. about 10 days ago.

Getting the following error :

 [Symfony\Component\Debug\Exception\FatalErrorException]            
 Call to undefined method Illuminate\Foundation\Application::share()

[2017-03-06 15:14:25] local.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Call to undefined method Illuminate\Foundation\Application::share()' in C:\laragon\www\broadsoft\vendor\maknz\slack\src\SlackServiceProviderLaravel5.php:27

I see a few forks that fix the 5.4 issue.

Thanks for the information! Since they do not have time to maintain the package (maknz/slack#82), we created customized SlackServiceProvider class that is simply changed share() to singleton().
We are planning to fork the package if other issue happens.

To use the customized Service Provider, please change
Maknz\Slack\SlackServiceProvider::class
to
Notify\Laravel\SlackServiceProvider::class
for 'provider' in config/app.php.

Let me know if other issue happens.
