Feature Request: Store Database local to the app

[Marthisdil]

To make the app portable, would it be possible to store the database folder locally (i.e. in the same folder as the app)? That way, can just copy the demeter folder whenever you need/want to move the app elsewhere and not need to worry about finding the database, creating a new one at the new destination computer, copy over, etc.

Just as a note for any possible contributors, the default would have to stay the current path to prevent a breaking change where the database cannot be found.
