MVP Popup Notifications Working

I'm unsure which will be more performant: A notification using a trimmed down version of the UI, or using them both, letting the browser cache them both.

In any case, here I've modified the normal UI to recognize when it's a popup, and change the UX accordingly in a few ways:
 - Hide the menu bar
 - Hide the back button from the notifications view.
 - When confirming the last tx, close the window.
