Previously, a race condition could cause DevTools to enter a state where it can't detect an application on reload. This was caused by a sequencing issue between the content script connection, the devtools panel connection and an event "backendReady" that lets DevTools know when a particular frame is ready to be inspected. This commit replaces the previously stored backendReady boolean with a promise, so that the devtools panel can eventually run a callback to connect to a content script when that content script emits it's backendReady message.

Angular DevTools UI
This module exports the Angular DevTools component. We render the DevToolsComponent within an Angular application running in Chrome or Firefox DevTools. This module of the application communicates with the Angular DevTools "backend".
