[new feature request] javascript-client-side check for has_online_operators()

[polymorphm]

I think it would be nice if there was a official-possibility check the operator via ajax (client side javascript)

my example of implementation:

• https://gist.github.com/1300629#file_has_online_operators.php

this allowed to use next code in client side:

• https://gist.github.com/1300637#file_webim_client_button.js

thanks! :)
