Use QEventLoopLocker to keep Spectacle alive for notifications

Stopped using setQuitOnLastWindowClosed(false) because setting it true
or false depending on the situation was too complex. Now we just create
a QEventLoopLocker when we make a notification and destroy the event
loop locker, which also automatically quits the application, when the
notification is destroyed. To close the windows, we use
SpectacleWindow::closeAll() instead of making them hidden. This
automatically closes Spectacle when the QEventLoopLocker has not been
created.
