Add new project db method, GetSalt, to get project salt. If salt
column is empty, return the sha-256 hash of the project ID. This
new method is used in metainfo endpoint ProjectInfo to return the
project salt to the client. This is backwards compatible because
the salt column is not populated yet. The updated endpoint will
do the same thing as the current endpoint.

everyone was importing it as dbx anyway. why should it be
named satellitedb? so yeah just pass the "-p dbx" flag.
