Title: Update step_05.ngdoc

_$httpBackend_ is a cryptic way to name variables. Because of this, even you had to write a comment about this why did you use it that way! This is crazy.

So, just making _$httpBackend_ as $httpBackend, and the local var $httpBackend to $http we can easily smooth this complexity.

Elegancy is the key.
