Experimental afhttprequest

The interface for creating HTTP requests is now even more intuitive:
[GET URL:@"/path/to/resource" parameters:nil success:nil failure:nil];

For a live example, see AFPost.m +globalTimelinePostsWithBlock:

Notes
- Subclassing AFHTTPSessionManager is no longer necessary, but initializing an AFHTTPSessionManager should happen in -application:didFinishLaunchingWithOptions: (see iOS Example).
- Because each HTTP verb is now a class, I renamed Post.m in the iOS example to AFPost.m
- Congrats on the marriage :)
