Set the Mac project file to reference protobuf-net in the ThirdParty folder, instead of the old DLLs folder in from the original main project
Fixed a typo that had crept in to MacGameView.cs
Fixed MacGamePlatform.cs so that setting full screen boolean to true or false and then using GraphicsDevice.ApplyChanges( ) will work instead of just error-ing (which is what it was doing prior to this fix - there were comments in the code indicating the lines that needed to be changed back - not however certain that this won't break something on other platforms - ie. other than Mac)
