Support for FCM

[kleisauke]

Will this package get support for FCM (Firebase Cloud Messaging)?

GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future.

See: https://developers.google.com/cloud-messaging/faq

At first look, I think it's only necessary to change the URL in this file.

-const SERVER_URI = 'https://gcm-http.googleapis.com/gcm/send';
+const SERVER_URI = 'https://fcm.googleapis.com/fcm/send';

@mwillbanks When is this going to be downloadable via composer?

[mwillbanks]

@bathan well, if you can download it separately and functionally test it that would be great. I am likely going to do it this weekend (I was on vacation last week and this week has been catching up on main work tasks).

@mwillbanks When are you planning to release this new FCM support update? When is this going to be downloadable via composer?

[mwillbanks]

@jaystepin I'll release it today.
