created function \"change_job_priority\" and \"remove_job\" (this remove_job function recieves a job number and returns structure distrenjob, it was made to assist the change_job_priority function)

I also fixed an error where add_job_to_queue wasn't updating its prev_job pointer, which would of resulted in the loss of jobs between head and where the new job is inserted.
