Floorplan ajax

hey @crissmancd, There's still a fair abount to do, but I'm making some progress on my end. I'm taking a break for a while, but this is what I have so far. I can merge this in later tonight if it looks reasonable to you.  Or, feel free to merge it in if you're still actively working on this.
I ripped this iui-steps div out since it wasnt in the design file I'm looking at. That mess with you? If so I can put it back.
