Support for angular 1.3.0

In angular 1.3.0 there was a breaking change, the return in controllers won't work anymore (https://github.com/angular/angular.js/issues/8876).
This simple change will fix it.
Merge pull request #44 from ocombe/patch-1

Support for angular 1.3.0
I normally try and test such change myself, but cannot really find the time for it. So in this case, will just merge the pool request, as I think it should work... considering the number of people claiming it appears to work...
