Avoid starting the notification thread twice
Starting the notification thread more than once can result in strange behavior. For example, when launching external commands, only the most recently started thread is stopped which results in the external command's screen output being overwritten by the notification bar. Currently, there are a couple of situations where the thread is started twice. As a first countermeasure, explicitly check whether the thread is already running (and terminate it) before starting a new one. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
