The Task API allows for an easy way to create long-lived tasks that
require reporting back to user with progress/logs. It will be used in
the upcoming game importing.
Object storage now works fully, with the permission system. It still
needs additional external endpoints for updating and deleting objects
from the API, but it is otherwise complete. Further tasks include
writing an S3 adapter.
New ObjectBackend class that requires implementors to specify a few
basic functions, and it handles the permission logic on top of that.
Hopefully there is enough abstraction to suite further use cases!
