Add Safari Native Push Notification Support

[mananshah99]

Alongside the desktop notifications, adding mac native push would be really useful for those who continue to use Safari.

This requires a Mac or iOS developer license though...

@Arcterus I think I have an active license from a year ago. I'll see if I can use it here.

Sounds good.
