Initial Release (v1.0.0)

This release is fully functional implementation of Google Music's API. It is (relatively) stable from initial testing and finally fixes the bugs with the Music Manager client.

This was intended to be a simple, stable release. However, it does not feature the following features that are still being completely rewritten from scratch:
-Consistent asynchronous model with .NET Framework 4.5.1 APIs
-Full implementation of the Google Music API (missing parts of both the WebClient and MusicManagerClient)
New progress reporting model
-Memory optimizations (better use of streams, GC management of LOH, etc.)
