ClassBot needs efficient way to run tests

Currently, whenever a new revision of ClassBot is released, all of the features need to get tested by hand. This is slow, messy, and inefficient. There should be a more automated way to run these tests. One way to go about this would be to create a second irssi script that simply joins the appropriate channels and runs the correct commands. It would then check the output from ClassBot to make sure everything is working properly. The pro to this is that it would require no modifications to classbot.pl. The con is that it would require a second irssi instance to run the test script.
