AI jib 3.0

This is my 3rd attempt at optimizing a jib for AI. It still has a ways to go, so I won't be testing it for a while, but I thought I'd post a few details here and update when I get a chance to try it out (with luck, as soon as this week).

I'm using aluminum tubing for a mast and fashioned some end pieces out of starboard plastic. I'll have it all put together tomorrow or Tuesday, and then I just have to figure out how to transport it...
