    general: Don't set rows as activatable by default
    
    The GtkListBox widgets were created by having all rows being
    activatable, which resulted in a visual glitch when clicked on them.
    
    Most of the rows in Tweaks shouldn't be activatable, so this commit
    provides a way for each tweak group to define whether rows should be
    activatable or not, defaulting to False.
    
    This fixes the visual glitch.
