pep8 fixes

adminlog.py: fix indentation to be pure tabs
adminlogbot.py: add blank line
config.py: add # noqa markers -- a tab is seen as 8 spaces, or two indents,
           so a tab indentation for a dict is seen as 'too much indentation'.
	   I think it makes more sense to ignore this message than to switch
	   to spaces for these few lines.
