Bug fix

Fix bug where redirects to files outside Basecamp had the url changed.

Security improvement

Security improvement: OAuth2 sets and checks a GUID state parameter.

First release

C# Wrapper to the BaseCamp API

Provides nearly all the functionality exposed by the BaseCamp API, in proper, type-safe C# classes.

Also provides lower-level calls that can accept and return arbitrary C# objects, or Json JObjects, if you need a call that isn't already included, or is undocumented.

Accredits with Basecamp using OAuth2.

Comprehensive set of unit tests which demonstrate how to use the API.
