Add support for chosen:search_updated event

[kir]

The event is fired on the original selector when Chosen’s search results are updated after typing the search term.

The event also includes a corresponding search_term parameter.

@kir Can you give us a realistic use case for this event?

[kir]

@tjschuck I'm using this event to update the list of items shown via selector, i.e. there is a delayed ajax request to the server which depends on the filter contents and I re-populate the selector with an alternative item set, depending on the filter.

Guys, any follow-up on this? I've used this patch in https://chrome.google.com/webstore/detail/checkvist-web-clipper/pheahjlflgbnajeilgglgcdlbkdckamf extension and it works nicely.

Unfortunately, I have troubles publishing the same extension in the Firefox add-on repository as they insist on using non-patched version of the libraries.

So I'd really appreciate a release with my patch.

Any prediction to release this feature?
