Add basic type definitions for express 4.x
angular.d.ts: new interface IServiceProviderClass

Instead of IModule.provider simply accepting an Function for a class
constructor, use an interface to enforce the type of class.
angular.d.ts: new interface IDirectiveFactory

Adds intellisense when constructing directive objects

Missed provider functions that return objects.  Ensure that they also
implement ng.IServiceProvider.
