Add convenience methods to proxy httpmock and handle success/error

[ReactiveRaven]

Adds handling for the following methods on $http:

• .get(url, config)
• .delete(url, config)
• .head(url, config)
• .jsonp(url, config)
• .post(url, data, config)
• .put(url, data, config)
• .patch(url, data, config)

Adds wrapper functions to make the promise returned behave more like the one from $http:

• .success(f(data))
• .error(f(data))

Hi @nielssj and @ReactiveRaven sorry for the delay. This code has finally been merged. Its the new version 0.1.5. I'm still working on adding a few more examples but the code is ready to be used.

Awesome, @atecarlos ! I don't have the time to check it out properly this week, but I just ran all the tests I made based on @ReactiveRaven's implementation and they still pass with your implementation.
