  The first commit changes it so that messages with level Warning and Error are always logged independent of the `-debug` setting. I think this is useful to make sure warnings and errors, which tend to be important, are not lost. In the future this should be made more configurable.

  Last commit changes LogPrintLevel argument order to category, severity: This is more consistent with the other functions, as well as with the logging output itself. If we want to make this change, we should do it before it's all over the place.
