Added Aiml edition table

Hello,

First of all thanks for the great work, I have been using program-o for my web site for a while and it's great. I have spent few times working on an aiml edition page, so I could edit my bot easily. I share this with you, maybe you'd like to integrate it.

It's based on teach.php & search.php. I put it in editAiml.php, so the other files remained unchanged. I used YUI 3 since I have some knowledge of the lib. The library itself is host on yahoo's CDN.
