Auto Screen Capture 2.2.0.2

If you're running the application on a laptop connected to an external hard drive (where you normally save screenshots to), but also save screenshots to the laptop's internal hard drive and then disconnect the laptop, the application would stop the current screen capture session. Now it will continue to run the current screen capture session even if the laptop has been disconnected from the external drive; it will simply not write screenshots to a drive it doesn't have access to. This means that screenshots writing to the laptop's internal hard drive will continue to write to the internal hard drive. The screenshots intended for the external hard drive will be written once its connected to the laptop again because the screen capture session has continue running. Also made some minor performance improvements on the saving of screenshot references.
