Frameworks: LockBeforeUnlock the new way (1/2)

Due that aosp removed the whole LockBeforeUnlock controll (show slider
lockscreen before an unsecure internal lockscreen) we must try to find
another way
without touching the security system itself. Long guess short solution,
lmao

here it is, next SlimKat feature

cheers

PatchSet:
- bring eca button to front in lockbeforeunlock mode to make
it clickable on slider lockscreen

adapted our 4.3 version to 4.4 and smaller fixes/code improvements
