/**
 * Mail User Interface
 *
 * As we do NOT want to connect to previous imap server, when a profile change is triggered
 * by user get_rows and ajax_changeProfile are not static methods and instanciates there own
 * mail_ui object.
 *
 * If they detect a profile change is to be triggered they call:
 *		$mail_ui = new mail_ui(false);	// not call constructor / connect to imap server
 *		$mail_ui->changeProfile($_profileID);
 * If no profile change is needed they just call:
 *		$mail_ui = new mail_ui();
 * Afterwards they use $mail_ui instead of $this.
