Since all games on a particular seed have the same starting player,
we should store this accordingly.
Note that this option is only used for old seeds (before 2020)
from the hanab.live database.
Regardless, we need to support this to be able to support these old
games.
Introduces a proper config file for db connection information
Also, connection now has to be explicitly initialized instead of this
being done on import: This is now done by the CLI function automatically
We now only use relative imports for files in the same directory
Also, only modules are imported, never classes/functions etc
Furthermore, main methods in package files have been removed,
since they do not belong there
