With this change, we provide a wrapper to `logging.getLogger`
in the `aurweb.logging` module. Modules wishing to log using
logging.conf should get their module-local loggers by calling
`aurweb.logging.getLogger(__name__)`, similar to `logging.getLogger`,
this way initialization with logging.conf is guaranteed.
