AJAX_setTopicStatus causes javascript error because addLoadEvent is not available

[_ck_]

Around line 600 in support-forum.php, function AJAX_setTopicStatus() starts with
if (is_topic()) {
which is not a good enough check, before it adds some javascript code to include with the webpage.

When addLoadEvent is called in the browser, it's not available to most users. I cannot figure out the correct logic, but non-members definitely do not have the required function loaded. Admin are the only ones that get jquery in a default bbpress install so maybe just test for that.

if (is_topic() &&  bb_is_user_logged_in()) {

is a simple but incomplete solution from the PHP side.

From the javascript side you could test for

if(typeof addLoadEvent == 'function') {

So I combined the two and change the start to this:

		if (is_topic() &&  bb_is_user_logged_in()) {
			$r = '<script type="text/javascript">' . "\n";
			$r.= 'if (typeof addLoadEvent == "function") {' . "\n";

and near the end you have to add:

			$r .= '	);' . "\n";
