Govet doesn't like functions that look like format handlers not ending in `f`, such as Debug() vs Debugf(). This is changing some of the new log handling to use 'f' function names to appease govet. Updated the implicit handling of including the client as an arg without being used in a format string. Now the client object simply has a Errorf function for logging errors and it adds itself onto the format string.
