More banner behavior tweaks

* Prevent the banner from being hidden while it's being animated onto the screen for the first time.

* Use the GestureHandler's onShowPress() function to determine when to show a highlight.

* Tweak the fling dismissal behavior so it somewhat takes into account the fling velocity (which often has a sign... or magnitude... that doesn't make sense).  Track a secondary velocity determined by how long it takes for a user to translate the banner.

* Replace the word "banner" everywhere in SwipableOverlayView with "view".

* Change the banner interpolator to make it feel more floaty when it is coming back to the center of the screen.

Submitted as NOTRY=true because the Java-only changed passed the android bots.
