Remove deprecated API

[devunion]

Hi, could you update the library to avoid of using deprecated API?

There is stack from FF 31:

"DEPRECATED: The widget module is deprecated. Please consider using the sdk/ui module instead.
Traceback (most recent call last):
File "resource://gre/modules/commonjs/sdk/addon/runner.js", line 113, in startup/<
run(options);
File "resource://gre/modules/commonjs/sdk/addon/runner.js", line 161, in run

let tbw = createBadge(browserAction, badgeState);

onClick: function() {
File "resource://jid1-bedgas3lmlydea-at-jetpack/toolbarwidget/lib/toolbarwidget.js", line 343, in exports.ToolbarWidget
let sdkWidget = require('sdk/widget').Widget(options);

That will be really helpful. Thank you!

This is on my to-do list, but it has a low priority. Pull requests are welcome.

When I published this module, Firefox's support for Chrome-style buttons was bad. Now the situation has significantly been improved, so I recommend to use the built-in sdk/ui modules instead.

Firefox has started an initiative to bring the features of the Chrome extension API to Firefox, see https://bugzilla.mozilla.org/show_bug.cgi?id=1161828.
