- had to make sure we don't snapshot until directive is fully applied
on a computer... otherwise there's races between loading the files and
truncating the write log.
- added a dirty bit to resources and a bool return to incrementing the
write log... don't snapshot if it returns false because that means
there's been no writes. (but make sure you close the storage transaction!)
- added the actually snapshotting routine which just fires every
<timeout> and serially snapshots everything.
- tweaked some logging
- added ability to get all tables in an org/db or literally all. I
think I just needed the "literally all", but it was natural to allow
it to be scoped to org or DB as well.
