[Joaquim Manuel Pereira Rocha <jrocha src gnome org>]

commit ba135aa3231bde2127d0797efcb2406df8102554
Author: Joaquim Rocha <jrocha endlessm com>

    Set the apps box's selection mode to none in the category view
    
    Otherwise it is possible to select a child of the box without actually
    activating it, which is unnecessary.
