    appDisplay: Properly check for TerminalEmulator in the Categories key
    
    get_categories() returns an unparsed string, not a list of categories.
    We need to parse the list by splitting on ';' to deterine whether the
    actual 'TerminalEmulator' category is in the list, rather than something
    like 'X-GNOME-TerminalEmulator'. It's an edge case, but I need to split
    the list properly for the new folders, so I might as well fix this.
