Push notification support

Would be great to have support for push notifications! Only thing keeping me from switching from my Epichrome implementation.

"While investigating, I discovered that Electron was not built on top of Chromium itself but only on a subset called Chromium Content (using libchromiumcontent), which is the core part of Chromium needed to render a web page. For example, it doesn’t include all Google APIs and Services built in Chromium and, ** unfortunately, it’s missing the Push Notification API & Push Service needed to receive push notifications**."
