[BJv2, 95%] Modify "swipe back to clock" to use swipe up to down instead of Lt to Rt.

NOT very helpful,
now with "swipe back to clock" using swipe up to down, then in "folder launcher", you cant scroll up

so,
the 4 lists of (always on, whitelist, blacklist, always off) should be extended to L to R, R to L, U to D, D to U, for BOTH "back swipe" and "swipe back to clock"

may be if "back swipe" works (1 step back, this never worked for me), a menu will be pop up upon the swipe and let user choose.
it WORKed, but only on apps that have an arrow in the Lt Upper corner.
so when compare to "swipe back to clock", this app brings you back to the clock on any screen.
