    shell-app: Base running state on "interesting" windows
    
    An app should be considered running if it has at least one "interesting"
    window, however the code considers an app running if it has at least
    one tracked window. This was fine while we were only tracking interesting
    windows, but since commit d21aa0d85fc325 this is no longer the case.
    So keep track of the number of interesting windows as well and use that
    to determine the running state.
