Using cmdline switch --debug doesn't affect config

[derek-keeler]

Setting --debug on the command line doesn't change config["log_level"] from info to debug, should it?

That's not a bug, but while checking I did find a related one. We want to set the log level as early as possible, so we set it as soon as we've got the args and before build_config() is run here.

But, it turns out that log_level in the config file is ignored. Command-line options should override config options, so we should set the log level in this precedence:

• DEBUG if --debug was used
• log_level from the config file
• INFO if neither of those was provided
