For modern chrome builds

"Working" in Chrome 32.0.1700.77 (MacOS 10.9.1) and with WP3.8. 
I've been manually updating values from options.html directly in local storage; will work to get it working via the options.html UI. ("permissions": "storage" in manifest doesn't completely fix it)

Also removed scheduling from the UI in popup.html.
