loglevel should be configurable

[Dieterbe]

it should be up to users whether they want date/time (and which format) in the messages, and which loglevel they want. this could be made configurable through the config file

[Dieterbe]

maybe we should add 2 variables to the config, something like:

logging_datefmt='%m-%d %H:%M:%S'
logging_level=logging.DEBUG

or even suggest the user to add something like this to the config:

logging.basicConfig (datefmt='%m-%d %H:%M:%S', level=logging.DEBUG)

Configurable log levels would indeed be nice to have. Patches are very welcome :)
