Fixes #634
Changed bot error message

Currently, when recovering from an exception raised by a module the
bot will sent out the exception signature via IRC which might
contain somewhat sensitive data like local path names.

This commit changes the message to a fixed string. The exception log
including the full stack trace is stored in a log file, so sending
the exception message trough IRC is not necessary for debugging.
