Alternating Background issue when selecting a gameobject in hierarchy

[khold93]

The "Alternating Background" flickers every time I select a new object in Hierachy.
I assume its updating on click and is redrawing the alternating background,
It only happens if the hierarchy is not fully visible it seems. Aka not showing all the gameobjects in the list.

You can fix this by setting HierarchyDrawer.temp_alternatingDrawed to false in the EditorApplication.Update callback.
