Add bookmarklet option to support all browsers

To run the bookmarklet in dev mode:
- `grunt bookmarklet_server`
- create a bookmark:

```javascript

javascript: (function() { var s = document.createElement('script'); s.src = 'http://localhost:9191/load_inspector.js'; document.body.appendChild(s); }());

````

Clicking on the bookmark opens a new window with the inspector.  Make
sure to unblock the popup.

This can also be used to debug the inspector (in the popup) using the inspector
extension.
