/*
Trying to figure out the API for creating a toolbar button

How do it in each browser:
Chrome
  manifest && chrome.browserAction...
Firefox
  widget.Widget({...})
Safari
  Info.plist

         | declarative | programmatic |
_________|_____________|______________|
Chrome   |     x       |      x       | Must be *both* & is a bit hacky
Firefox  |             |      x       |
Safari   |     x       |              |
_________|_____________|______________|

All support multiple icons
*/

// Programmatically
xio.ui.toolbarItem({
  ...
});

// Declarative
// In Safari, which requires a 'command', the command could be auto generated
//   safari.application.addEventListener('my-item#clicked', function () { ... });
{
  ...,
  toolbar: [
    {
      id: 'my-item',
      icon: '/res/kitten.jpg',
      tooltip: 'A Kitten!'
    }
  ]
}

Doing either would require some kind of offline processing to turn json into plist, but that goes against the goals of the library. Looks like this isn't possible.
