fb: add accessibility events to lockscreen slider and shortcuts (1/2)

beside that it is nicer for ppl using talkback eg and get clear
instructions this solves as well a fc in settings lockscreen targets
when using accessibility services

Change-Id: I03014892d30491b1d126e61a6891393416e4b1be
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...

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

Framework: Notify User Interaction on Unlock

If user is unlocking or opening an app...
	Notify so the screen timeout is
	reset.

PS2: Dependency

Frameworks: More Lockscreen Colors (1/2)

No content resolver?  Colors EVERYWHERE!!!

PS2: Code clean-up && fix avatar

	border color (AOSP was never
	using their own color value
	either <_< so fix that as well
