auto-accept honor code

You probably want to rewrite this patch, as I don't know python (no joke). It works but its ugly. This patch adds the option --honor-code to auto-accept the honor code. Also, if course isn't found, it tries appending -001 to the course name.

Many courses now redirect to coursename-001 for the first time its taught, -002 for the second time,etc. The script should search for this automatically.
