Going from 0.0.0.dev4 to -> 0.0.0.dev8 zodbtools:

- Stabilized `zodb dump` format and layed ground for `zodb restore`;
- Taught `zodb analyze` to work with any ZODB storage (instead of being
  FileStorage-only tool) and to analyze a particular range of history
  (instead of crunching data for days on a large database);
- Added `zodb commit` tool that is handy in testing;
- Added ability to specify tid ranges in human-readable format, as in
  e.g. `zodb analyze data.fs 2018-01-01T10:30:00Z..yesterday`.
- Progressed on Python3 support.
