Fix for Angular 1.3 http interceptor api change

[vik-singh]

Angular 1.3 deprecated the old $http interceptor API - this change fixes the server sent notifications - New API is described here: https://docs.angularjs.org/api/ng/service/$http#interceptors

Does this brake support for angular 1.2?

[vik-singh]

@JanStevens Yes - fully tested with angular 1.2.x - I believe the API was changed long before 1.2 but old API wasn't fully deprecated until 1.3.

Hello,

Finally got the time to see the changes you made. I see you made changes in the build directory instead of the src directory. The distribution is created with grunt and will overwrite any changes you made in the build directory. Can you please commit your changes to the src directory?

Thanks!

I changed src/growlFactory.js - then I ran grunt and built the project and committed changes to the build directory too. So the changes were committed to src first (look at c5b5a89) - the subsequent commits were simply to build correctly.

Ha my bad! thanks for your contribution!
