Fixing Mac OSX Chrome notifications for version 30.0.1599.101. Discovered that in 30+ createHTMLNotification returns undefined; so updated code per example found at: http://jsfiddle.net/dandv/wT26x/1/ … should the old still be supported? Not sure.
chrome.tabs.getAllInWindow depreciated in favor of chrome.tabs.query per http://developer.chrome.com/extensions/tabs.html
Updating notification icon URL to be the one stored with the extension.
