Add slide before unlock to gesture

While pattern lock has slide before unlock, let's add it to the gesture
unlock as well.

Add "Enable Widgets" option and fix "Make Gesture Visible."

The "Enable Widgets" option should show up under gesture unlock. And by
default, the "Make Gesture Visible" option is enabled, but the first
time it's set up, the setting shows up unchecked, even though it's
enabled.
