Version 1.17

Version 1.17 is now released, which fixes a bug in the Save location chooser (gave error if the folder didn't exist), and a bug on some devices where the photo was being taken out of focus.

New options are added for volume keys: focus, and switch auto-stabilise on/off. Changing flash mode is now supported while recording video (so torch can be switched on/off).

Some minor improvements to the UI look: removed the square from the photo/video icon, and using some more natural red/green/blue colours.
