Persistent Database Storage

[kalimar]

For Hacktoberfest, yours truly revamped our code base so it would be easier for new people to contribute to the app. That mostly worked but unfortunately I also wiped away database persistence. This means that any data saved to a Terrastories app gets wiped away when the app shuts down. Not very useful.

User Story

• Terrastories needs persistent database storage. This means that if you shut down the app, the data (images, video, audio, metadata) will persist.
• A field technician should be able to run a command that allows them to export the database from the computer running terrastories to an external storage device (hd, thumb drive, etc).
• Nice to have is a user interface that allows the field technician to perform the same database export.

Validation

• [ ] Add data to a terrastories instance
• [ ] Shut down application
• [ ] Export and inspect terrastories database on external storage device.

@sudo-bmitch is currently working on this. Per voice conversation, he will push his work to Github and I will then test nag someone to validate and then merge. cc @rudokemper @mirandawang
