[review] pre-release checklist

[ShaunSHamilton]

These are the main components of the app needing review before 1.0.0.

• When a new update is released, it is required to be downloaded before continuing
  • Unless in the middle of an exam attempt
• Downloading and installing an update is smooth - no app crashing
  • Test logged in and logged out
• An incompatible device may not get past the splashscreen
• An incompatible device may not start an exam
• Only a valid token allows past the login screen
• During an exam, if a request cannot be made, the screen is paused until connection is re-established
• If an exam attempt is started, and time still remains, clicking the same exam takes the Camper back to the same attempt
• If a device camera is disabled during an exam, the exam is paused until the camera is re-enabled
• If an exam attempt is too recently finished, trying to retake it shows an error explaining why another attempt may not be made
• If a Camper has not completed the prerequisites for an exam, it should not be possible to attempt to start one
