DataHandler does not set "-1" for versioned records in workspaces
anymore, thus making it a lot easier to find the real PID for a versioned
record without always having to fetch the live version for it.

This is ground-breaking, as this opens the door for a lot of improvements
when accessing versions via overlays.

An upgrade wizard will migrate all pid=-1 records to their equivalent
pids, and discard all already published / archived versions.
