Added some sketchy code to allow the bot to run on perl 2.0 and not die with a runtime error if there is no config file.

Allowed starting with perl 2.0, though I don't know any better way to implement this. Also made it check to see if the config file exists instead of dying with a runtime error.

In case you couldn't figure it out, I don't know perl, I just needed
this to run on perl 2.0 and also noticed it throwing runtime errors.
