Making angular-loading-bar be aware of 3rd party libraries using XHR requests by listening for events.

Added feature: Be able to fire start / end request events from non-angular 3d party libraries that also do XHR requests so that the loading bar it's also aware of these requests.

In case that you are using Angular in combination with non-angular 3d party libraries, you can now fire custom 'cfpLoadingBar:start' and 'cfpLoadingBar:done' request events.
