Database config/init overhaul.
This contains some not-very-atomic changes:
* Get rid of `get_session_class()` function and return to global `Session`
class approach.
* Primary database `Session` is now configured as part of command
initialization, by default.
* Make `config` object available to subcommands, and `Daemon` instances
(the beginning of the end for `edbob.config`!).
* Add `--stdout` and `--stderr` arguments to primary `Command`. These are
in turn made available to subcommands.
* Overhauled some subcommand logic per new patterns.
* Get rid of a few other random references to `edbob`.
* Added and improved several tests.
* Added ability to run tests using arbitrary database engine.
