[gnome-shell] Fade in alt-tab popup, adjust timings

[Florian Müllner <fmuellner src gnome org>]

commit 6e09cc5fc85f9c02a01ecb2de1f9d9f1a342be51

    Fade in alt-tab popup, adjust timings
    
    The design calls for item to not appear abruptly, but not too slow
    either - 100ms seems to be a good sweet spot for elements which are
    supposed to appear "instantly".
    Add a fade effect to the alt-tab popup and set the timings for other
    fade effects to 100ms.
