Separate Listview & System Anim in Pref. + ACCESS_SUPERUSER

1) Added "android.permission.ACCESS_SUPERUSER" permission.
2) Separate ListView Animation and System Animation in preferences
(to get ready for listview anim blacklist and system animation controls)
ListView Animation Blacklist (1/2)

Added Preference + Activity with dialog.
Combine ListView Cache & Animation

Doesn't make sense as cache is meant to aid the extra animation. If
blacklisted, let app control persisting cache themself.
ListView Animation Blacklist (2/2)

-Added blacklist checker in xposed hook (ListViewAnimationMod.java)
-Cleanups (other classes)
