WIP - have added LightInject as a fast and tiny IoC container that is embedded. Have updated all required SingleObjectResolverBase and non lazy ManyObjectResolverBase to use a Container implementation. Have updated the boot managers to use IoC to instantiate all their requirements. This is so much nicer now by using IoC to ctor all of the objects in these resolvers we can get ctor injection OOTB so no more singletons. Need to create resolver to support the lazy resolver with IoC next. Updated IContentFinders, IThumbnailProviders to use ctor injection.
