decode and encode CGI:IRC and PHP:IRC user id in X-Chat

First version with basic decode and encode.

This perl script lets you decode and encode the id of CGI:IRC and PHP:IRC users.

encode ip:
/PHP:IRC-encode 127.0.0.1
encoded 127.0.0.1 to 7F000001

decode id:
/PHP:IRC-decode 7F000001
decoded 7F000001 to 127.0.0.1

There isn't much help since there is not much to it. More is planned for the script for more details about the user but for now the main goal was to have something simple that works.
