Add double tap sleep feature to secure lockscreens.

In its current state double tap works on the status bar on unsecure

lockscreens.

 - pin and password: double tap the text entry view.
 - pattern: double tap anywhere on the pattern view.

Patch Set 3:
 - add to slide lockscreen(glowpad): double tap glow pad to sleep
