updated httpd.c to use different dirs for sites and vhosts

updated gopherd.sh to use the new rdns script
rdns script just wraps dig -x and outputs a real hostname instead of one ending with a '.'
rebuild.sh got a cd added to the top so it can be run from somewhere else
mime-type got an error line commented out.
