	SWFUpload.SWFObject Plugin

Summary:
		This plugin uses SWFObject to embed SWFUpload dynamically in the page.  SWFObject provides accurate Flash Player detection and DOM Ready loading.
		This plugin replaces the Graceful Degradation plugin.

Features:
		* swfupload_load_failed_hander event
		* swfupload_pre_load_handler event
		* minimum_flash_version setting (default: "9.0.28")
		* SWFUpload.onload event for early loading

Usage:
		Provide handlers and settings as needed.  When using the SWFUpload.SWFObject plugin you should initialize SWFUploading
		in SWFUpload.onload rather than in window.onload.  When initialized this way SWFUpload can load earlier preventing the UI flicker
		that was seen using the Graceful Degradation plugin.

// SWFObject v2.1 must be loaded
	
var SWFUpload;
if (typeof(SWFUpload) === "function") {
	SWFUpload.onload = function () {};

swfobject.addDomLoadEvent(function () {
		if (typeof(SWFUpload.onload) === "function") {
			setTimeout(function(){SWFUpload.onload.call(window);}, 200);
		}
	});

SWFUpload.prototype.initSettings = (function (oldInitSettings) {
		return function () {
			if (typeof(oldInitSettings) === "function") {
				oldInitSettings.call(this);
			}

this.ensureDefault = function (settingName, defaultValue) {
				this.settings[settingName] = (this.settings[settingName] == undefined) ? defaultValue : this.settings[settingName];
