MyDash: restore dash actor internal top alignment after 3.6 release.

The centering of the dash is managed by a further container actor in my
extension. Since Gnome-Shell 3.6 the upstream dash is also centered but the two
centered boxes were causing the misplacement of the dash actor.
myDash: remove accessibility shortcuts duplicate after 3.8 release.

Gnome-Shell 3.8 compatibility.

Since Gnome-Shell 3.8 the accessibility shortcut of the dash is registered
inside the dash code. However I've been extending it adding show/hide callbacks
inside the dockedDash class. Thus I remove it.
MyDash: Use new 3.8 menu-state-signal instead of my old custom code.

Note: isMenuUp variable was removed from appIcon. Some code need to be changed
still.
myDash: Since 3.8 DashItemContainer is a proper St.Widget.

Following upstream code this means that the "Chinese boxes"
(ShellGenericContainer actor inside the DashItemContainer class) has gone and
the code is simplified.
myDash: add option to display applications button at top of dash.
myDash: drag correctly when height is expanded.

Correctly drag icons when the height of the dash is expanded. Compute the total
height of the icons by summing their heights instead of using the container
height.
