config option for loading bot "plugins"

as it turns out, i can't use a module __init__.py to load bot stuff, if
that code would refer to django models, because the django code will try
to do stuff before the apps are initialized, and then the entire house
of cards crumbles apart.

so, i will explicitly load these bot "plugins" separately, after the
modules proper are all initialized
