Listen to browser notifications

[JStruk]

The "timer up" notification is being displayed based on what feels like a really hacky solution. Right now, the code constantly responds to the webpage title changing, and assesses the state of the app. If it's the first time we've changed from "Mob Timer" to "4:59 - mobtimer", we know the timer has started. Consequently, when the title switches from "0:00 - mobtime" to "mobtime", we can assume the timer has ended, and send the notification here. There are many many downfalls to this logic, the biggest complaint being if the functionality of the app ever changes and the titles are updated differently, this stands to break. This could be fixed by listening for the actual notifications being sent by the app and passing them along to the IDE.

AC:

• Using some sort of listener to handle the actual browser notifications being sent, relay these notifications to the user through the IDE notification system

Notes:

• The code listens to the title through a CefDisplayHandler, which requires an onTitleChange handler. I wasn't able to find a handler within the Java-wrapped chromium framework that listens for notification events. If this exists somewhere, it would be perfect for what we need to do.
