Handle camera not available in webcam mode #7

The camera may not available to the app in Webcam mode for a number of reasons (there may simply not be a camera or it is in use by another app). Currently, our app shows empty space and leaves the "SNAP" button enabled. This issue tracks handling of camera issues and provides useful defaults and state handling.

Codes added to detect webcam not available and disable buttons and display an alert.
