/**
jQuery based implementation of the Plupload API - multi-runtime file uploading API.

To use the widget you must include _jQuery_. It is not meant to be extended in any way and is provided to be
used as it is.

@example
	<!-- Instantiating: -->
	<div id="uploader">
		<p>Your browser doesn't have Flash, Silverlight or HTML5 support.</p>
	</div>

	<script>
		$('#uploader').pluploadQueue({
			url : '../upload.php',
			filters : [
				{title : "Image files", extensions : "jpg,gif,png"}
			],
			rename: true,
			flash_swf_url : '../../js/Moxie.swf',
			silverlight_xap_url : '../../js/Moxie.xap',
		});
	</script>

@example
	// Retrieving a reference to plupload.Uploader object
	var uploader = $('#uploader').pluploadQueue();

	uploader.bind('FilesAdded', function() {
		
		// Autostart
		setTimeout(uploader.start, 1); // "detach" from the main thread
	});
