We now have a Glimpse (Plugin) Tab :smile:

- New Scope and Provider Public/Private key interface.
- New Scopes interface.
- New Glimpse Tab to display the registered Providers.
- Sample Mvc Auto website has the glimpse pluging added, to test this out.
Google and Twitter Fake Providers weren't passing back the state. Does now and doesn't error.
FakeProviders have all been replaced by one single FakeProvider and more Provider tweaks.

- All the fake providers have been deleted.
- New FakeProvider class. Has default AccessToken and UserInformation results but can manually be overwritten.
- Slimmed down more of the Providers by moving more stuff up the inheritance tree.
The static ConfiguredProviders variable was screwing things up and removed the IncludeFakeProviders config setting.

- Replaced the AuthenticationService's ConfiguredProviders property from static to an instance variable.
- Removed other static properties that were referencing that static property.
- Removed the IncludeFakeProviders from the ProviderConfiguration class.
