* Added new features to the Overlay:

- Show/hide overlay button. Tapping this button will quickly hide the overlay. Long-pressing the button

will completely remove the overlay.

- Take Screenshot button (requires the Gesture Navigation Xposed

module)

* Added a new Bulk Delete function. (Locked accounts will not be deleted.) NOTE: since this operation can be potentially very destructive, you will always be asked to confirm bulk deletes.

* Various bug fixes and enhancements
