Allow Menulet to Toggle Custom AC/DC State

[GoogleCodeExporter]

Mac OS X 10.8.4
NoSleep 1.3.3

I would like a preference added so that when the menulet is clicked, it can 
toggle a custom AC/DC state. Currently, clicking on the menulet prevents sleep 
on both AC and DC power. I would like to click the menulet and have it prevent 
sleep on only AC power, but I would still like my Mac to sleep on DC power.

Thanks for such a handy utility!
