Rogue directories handled better...

Tiniest of bugfixes for handling rogue directory names. Query on "" returned all. This is fixed.

---

Wrapping up any commits since 0.5.0-BETA.

Main issues looked at:

List Display (count output in HTML tables had regressed to childlike state)
Date handling improved (no third party libraries)
Report output if no-hashes
Rogues and blacklists further improved
New version class should help me up version properly from now!
Report all the bugs - still the most valuable thing you can do to help push this project forward.

Still looking for participants in i18N exercise, converting this table of strings and archivist descriptions: https://github.com/exponential-decay/droid-siegfried-sqlite-analysis-engine/blob/master/libs/internationalstrings.py
