Ok, NIDS is getting better and better, and I went ahead and cleaned up some
exception related code that's been annoying me. You should no longer have to include any exception header explicitly for normal operations, every class that has it's own exception to throw defines it in it's own headers. This may break some code that uses libbu++, but it's an easy fix, just delete the include for exceptions.h. Sometime soon I would also like to move from Bu::ExceptionBase to Bu::Exception, but that will affect a lot more code than this change did.
