[Autofac] Registration extensions
- Added some extensions: InstancePerSite, InstancePerWeb, InstancePerRequest
Merge branch 'feature/dynamite-container' of https://github.com/GSoft-SharePoint/Dynamite-2010 into feature/dynamite-container
- Had to patch up the new ChildScopeFactory so that the scopeKindTag is used to tag the child scope (with a SPLifetimeTag value) instead of with the scope's unique ID. See RegistrationExtensions for how the scopeKindTag is used.
