src/*.vala: make the 'silent mode' switch item & action QMenuModel compatible

    QMenuModel, inheritting code from GTK, will consider the menu item not
    "activatable" if the item's "target" [1] doesn't match the corresponding
    action's parameter. Since we take a boolean as action's parameter (and
    we can't change action's parameter easily since it's semi-public), we
    instead have to pass "target".

    Taking a page from the slider menu items, pass "true" as the target
    will make QMenuModel considers the item activatable and reflect the
    right state.

    [1] i.e. the parameter to pass when activating the action. See
