SwipeBackLayout: Blacklist (1/2)
As we know, many apps do not support Swipe Back Layout now. If enable Swipe Back Layout on these apps, they may not work. So now I imported a Blacklist feature to let user choose whether to disable swipe back layout on some apps or not
This patch contains a set of functions to read/write blacklist for Swipe Back Layout. Another necessary patch is in packages/apps/Settings.
SwipeBackLayout: use "another" way to perform blacklist
This will not cause permission problems.
