/**
* Returns link to remote action
*
* Returns a link to a remote action defined by <i>options[url]</i>
* (using the urlFor format) that's called in the background using
* XMLHttpRequest. The result of that request can then be inserted into a
* DOM object whose id can be specified with <i>options[update]</i>.
*
* Examples:
* <code>
* $ajax->link("Delete this post", "/posts/delete/{$post['Post']['id']}"
* array("update" => "posts", "loading"=>"Element.show('loading');", "complete"=>"Element.hide('loading');"),
* "Are you sure you want to delte this post?");
* $ajax->link($html->img("refresh"), '/emails/refresh',
* array("update" => "posts", "loading"=>"Element.show('loading');", "complete"=>"Element.hide('loading');"),
* null, false);
* </code>
*
* By default, these remote requests are processed asynchronous during
* which various callbacks can be triggered (for progress indicators and
* the likes).
*
* The callbacks that may be specified are:
*
* - <i>loading</i>:: Called when the remote document is being
* loaded with data by the browser.
* - <i>loaded</i>:: Called when the browser has finished loading
* the remote document.
* - <i>interactive</i>:: Called when the user can interact with the
* remote document, even though it has not
* finished loading.
* - <i>complete</i>:: Called when the request is complete.
*
* If you for some reason or another need synchronous processing (that'll
* block the browser while the request is happening), you can specify
* <i>$options['type'] = synchronous</i>.
*
* You can customize further browser side call logic by passing
* in Javascript code snippets via some optional parameters. In
* their order of use these are:
*
* - <i>confirm</i> :: Adds confirmation dialog.
* - <i>condition</i> :: Perform remote request conditionally
* by this expression. Use this to
* describe browser-side conditions when
* request should not be initiated.
* - <i>before</i> :: Called before request is initiated.
* - <i>after</i> :: Called immediately after request was
* initiated and before <i>loading</i>.
