Fixes to Game startup when using a unit test runner.
The Content.RootDirectory cannot be absolute.
Removed local directory reference.
Using AppDomain.CurrentDomain.BaseDirectory seems to be a more reliable way of getting the working dir.
I was wrong.... Content.RootDirectory can have an absolute path.  MonoGame needs fixing here.
Game takes care of disposing GraphicsDeviceManager.
Removed old shader files.
Fixed shader format to write the shader code length as 32bit integer.
Incremented MGFX version to 5.
Rebuilt stock effects to MGFX version 5.
A better error message when a ContentTypeReader can no be found using Type.GetType

This change has been made in response to a common problem when porting projects. If you suffix your project with the platform name, eg MyGameTypes.Android, this defaults the Assembly name and resulting dll to MyGameTypes.Android.dll. Content types in this assembly can then not be reflected as the Xnb files were build against the project MyGameTypes.dll and hence have a mis-matched full type name.
