Title: feat(logger): Log errors with console.error (defaults to stderr).

Log errors, by default, to a new jog4js appender, the std_appender. This
new appender logs ERROR level events with console.error, and all other
events with console.log.

This std_appender is largely based on the console appender.

Closes #1011
