Working on AutonomousServices basics.

- Created some ReadOnly business classes for enabling/disabling the
  Autonomous service manager. Also for investing in a service.
- Added a test in the .Tests for the service manager. I'm just trying
  to get it to work in the tiniest fashion.
- Took out PostSharp stuff. It's nagging and not worth the effort at the
  moment. Would be nice, but the Silverlight not being free is costing me
  time and complication. It won't build without it and I don't want to
  troubleshoot every time just for that.
