Add an animation to pane entrance/exit (#7364)
Adds an entrance animation when panes are created. This animation can be
disabled with the `disableAnimations` global setting. 

Although the XAML animation documentation was pretty heavy on the _do it
in XAML_ route, our panes are created pretty much entirely in code, so
we've got to create the animations in code as well. 

200ms as the duration of the animation was picked _super_ arbitrarily.
300ms felt too long, and 166ms felt like it was only visible for a
single frame.
