Add support for injectable functions provided as constants

For example: when providing a resolve function to ui-router (maybe also the angular router) dependencies are injected by the router machinery, rather than globally, such that $state and $stateParams dependencies are populated correctly. Defining the injectable function as a constant, saves having to package it up inside the context in which it is being used.

```
angular.module('foo', []).constant('resolveFunction', function(dep1, dep2) {})
```

Start by reading the repository's AngularJS dependency-injection annotation pass and tracing how functions provided through module constants are handled. Determine the expected behavior for a constant containing an injectable function, including router-supplied dependencies; done means that function is annotated correctly without wrapping it in another context.
