    Improve the sorting order on the Installed page
    
    Previously, the sorting algorithm would take into account the install
    timestamp, which happened to be 0 for most apps. But not all, so some
    apps would seemingly randomly move to the bottom of the list after
    reinstalling (and a timestamp > 0 through that).
    
    Fix this by simply sorting by name.
    
    Also, while at this, make sure the sorting algorithm treats upper and
    lower case letters the same.
