Fix crash from lack of CL credentials

Reported by user, need to reproduce

So it took a few steps, but I essentially was able to delete everything related to courtlistener from the settings.ini file and the casebot.py file and after I did that I was able to run the program. My edited versions of the files are attached.

Casebot minus CL.zip

I'm confused. Are you trying to run casebot without any credentials for CourtListener? It seems like a crash is perfectly reasonable in that case? If it's working without credentials, that's because "anonymous" users can make a few queries before they hit their usage threshold. That's not a good way to use the API though in deployed code because it will soon fail...

(I'm the maintainer of CourtListener, BTW.)

@mlissner IIRC, Casebot has run fine without CL credentials, but yes, it would be limited eventually. In practice, this may not happen because Casebot use is likely very low volume.

@mlissner noted, I had had trouble getting CL to authenticate properly so this was a fix

Probably true. It goes by IP address if you're not logged in, so it probably would be fine without auth. I still encourage it because it makes my life easier, but you could probably get by without.

Can I help make it work? It should be very easy. It's usually just a header with the token in it.

@mlissner Casebot does authenticate to CL if you give it the token in the .ini file. I just made it optional. Will take a look at @jordanlcouch's files later to see what's up. Thanks to both of you!
