Feature Request: Turn on Scope Validation by default

[burningice2866]

As of May 10th, newer versions of the Microsoft Dependency Injection has turned on scope validation by default (https://github.com/aspnet/DependencyInjection/releases/tag/rel%2F2.0.0-preview1) which i believe would be the right thing to do in C1 as well as long as we're using version < 2.0.

This requires a simple change to this line https://github.com/Orckestra/C1-CMS-Foundation/blob/dev/Composite/Core/ServiceLocator.cs#L25, where true is passed to the BuildServiceProvider method.

I'd be happy to send a PR if you agree in making this change.

Please do - optimal if you can run the nightwatch tests and check they pass okay.

Looking closer at the aspnet/DependencyInjection#481 thread, it turns out they are only enabling Scope Validation when the application is running in Development Mode which i've updated my code to mimic by looking at the Debug Compilation Flag.

This makes sense since Scope Validation has a slight performance overhead and its mainly during development you want the extra checking to see if you messed up in one of your service registrations.

@mawtex ... and then what, something i'm missing here?
