fixed gopherd's LFI and added excuting files.

httpd had flushing issues.
realpath is new! does what it says. gives absolute path of a file.
deddos, peerip, peerip.pl, were laying around elsewhere.
gethostbyname got a new trick. can do decimal addresses among other things.
hop0 is a shell script that gets what IP will be put on the source address of outgoing packets sent to $1. rtfs.
