Adds an option to override RemoteViews transition.

This change adds a configuration option,
"config_overrideRemoteViewsActivityTransition", which is false by
default and true on watches.  If it's true, when a RemoteViews
is clicked, it will use a new attribute on the active window animation
style, "activityOpenRemoteViewsEnterAnimation", to determine
the entry transition to use, instead of the current hard-coded
default.
