Using AUI in the demo

[Robin Dunn]

I've applied most of Andrea's demo patch, which you can see in the 
latest preview build, and I'm curious how you feel about using AUI in 
the main frame.  Is the wow-factor worth the potential confusion of how 
to use it?  (Such as somebody clicking the X on the demo tree pane.) 
Could the non-native aspect turn off some folks?  Is it useful?
