Doug Blank ad3dcb8d13 Hide db._select(); Refactor db._tables; QuerySet; tests and bug fixes
db.select() has become db._select()

This commit refactors database._tables so that they can work properly
after a proxy or filter has been removed.

It adds abstract API called QuerySet which allows a variety of
selections and ordering of data.

Logging was added to sqlite to better see db access.

Additional fixes:

* clearing GenericDB._directory
* test_util_test off-by-one error
