Add get_bot_config (for debugging dumps).
Allow config sqlite name as wormgas constructor argument.
Move logging setup out of main and into wormgas constructor.
Necessary fixes to make an empty unit test succeed:

   * Added default_bot_config to initialize required botconfig
     db values.
   * Special-cased the empty string for the ignore regex to prevent
     it from matching every input line.
   * Added wormgas.stop to release file handles -- without this we
     can't clear the test config DB after every test.
Add 8ball unit tests. Add default for 8ball cooldown to botconfig.

I messed up and made the unittest file with tabs, so I'm fixing that in
this commit too.
Add moderator and admin-related methods to dbaccess.
Add config unit tests.
