Edited Feature: Add GlobalConfiguration.Configure that calls EnsureInitialized for you [1218]

Instead of writing:

// Global.asax.cs
WebApiConfig.Register(GlobalConfiguration.Configuration);

// WebApiConfig.cs
{
...
// Do not add any code below this line.
config.EnsureInitialized();
}

Do:

// Global.asax.cs
GlobalConfiguration.Configure(WebApiConfig.Register);

Where GlobalConfiguration.Configure is a static method that takes in a callback and, after calling it, calls EnsureInitialized for you, like so:
public static void Configure(Action<HttpConfiguration> configurationCallback) {
configurationCallback(GlobalConfiguration.Configuration);
GlobalConfiguration.EnsureInitialized();
}
