[Plugin: Events Manager] Event manager 3.0.92 breaks WP 2.9

Event manager breaks page if used on WordPress<3.0 because of is_super_admin() function which has been introduced in WordPress 3.0

I made a quick fix in em-functions.php:

function em_verify_admin( $user_id = false ){
	    if(function_exists('is_super_admin'))
	        return is_super_admin($user_id);
	    return false;
	}

This is just quick and dirty workaround. Developers should avoid using new functions and check their code in older versions of WP.

Right now version 3.0.92 is compatible with WP 3.0.0 and up.
