Remove obsolete auto AI reload feature
Random miscellaneous/cleanup stuff:
* Log (ignored) invites too (why not?)
* Typo corrections
* Formatting adjustments
* Some extra commenting
Use twisted's rebuild support instead of doing
reloading the hard way; make setting NikkyAI's
nick hopefully more robust
Force output lines to appear in proper sequence
even with multiple simultaneous outputs are
generated; fix some existing issues with
initial response delay setting not being properly
honored
