Bug: standalone gallery freeze while closing picture

[andi34]

Open standalone gallery. Click on a thumbnail to see the full-size image. Close the image.
Gallery freezes.

Problem is inside the photoinit.js:

        gallery.listen('destroy', function () {
            rotaryController.focusSet('#gallery');
        });

Rotary controller is not added to standalone gallery yet.
Rotary Controller should be disabled in standalone gallery or only be used on standalone gallery if enabled.

PR #253 fixes the crash and fully implements rotary button support - can some pls try it out ?
