Allow notification mirroring of Join API notifications
I realize that I could use the API to send notifications to multiple devices (e.g., notifications of additions to Android Police's RSS feed) but I'd like for my phone to be the "master" device. If I set up the notifications on multiple devices, I'll have to dismiss them on each. However, if these notifications were mirrored from my phone to the Chrome extension, I'd be able to view either on my phone or on the computer and dismiss once from either location.
