Plugin doesn't honor 'disabled' attribute on child OPTION tags

[wchrisjohnson]

The underlying SELECT used for this plugin has many child OPTION tags, each of which supports a disabled attribute that is set to a boolean - true or false. The plugin doesn't honor that attribute, and allows the user to add or remove items at will from either list witout regard for whether each option is enabled or disabled.

this is in the TODO list. Please, avoid using the "disabled" attribute at the moment. A quick fix would be to add an "nodeInserted" event callback and fiddle with the given DOMElement... but this should only be a workaround until the widget officially support it.
