Storage location rework

[IamSebastianDev]

Feature Request

Describe the feature you would like to see added:

Right now, the user has to explicitly choose a storage directory, and the directory can only be inside the current projects folder. This implementation has several issues, that should be fixed by reworking the storage location implementation.

Why would this feature be a good addition:

All data stored can only be inside the current directory, as the storage location is calculated from the project root. This means that multiple projects cannot access the same data, which might be desirable, but will lead to issues with a planned database explorer tool.

Additional information:

A additional flag could be added to the init object to specify if the data should be inside or outside the project.
