Close photo-view with swipe down or up.

When looking att photos in "full screen" you need to press Done in the top right corner to exit back to the gallery or log. Here it would be nice if you could just swipe down or up on the photo to close it instead of needing to push the Done-button, most of the iOS-apps that I use that shows photos in full screen has this kinda feature and I like it a lot.

This was previously possible in Cachly, but with some recent iOS 13 changes it looks like I accidentally blocked that gesture. Sorry about that, I will fix that in an upcoming version.
