Samples improvements

The part which I needed
to improve is the ApplicationBlock where I changed the OAuth2 classes'
structure a little and extended them with a lot of useful
functionality, like adding many Facebook and WindowsLive scopes,
fields, structures including the asked-by-many easy to use birthdate
and avatar url getters. I have also implemented the Google OAuth2
authentication and created one common interface for all 3 Graphs in
the code (which has the common properties like Id, FirstName,
LastName, etc.), so the authentication code became really simple if
you use my version of your ApplicationBlock.
