Add possibility to swipe between photos

[stsdc]

Would be nice to be able to swipe photos when they're open at full.
Currently it is needed to go back to grid view to choose another photo.

Probably, It will require a specific prefetch strategy e.g. if photo_002 is open then photo_003...004 started to fetch.

I don't know how to implement swiping in Android. If you (or anybody else reading this) knows how to implement it, feel free to drop some advice.

When you download a photo in Fudge, it downloads a full resolution copy and lets you preview it. Fuji's Camera Connect app downloads a heavily compressed 'thumbnail' and lets you view that. Then, if you want to save the photo, it will download the full res photo.

Given my use cases (I took few photos, I want to view and and download some on my phone) I think my current approach is best.

The reason I mention this is because it takes 3-10 seconds to download a single photo, and I don't see how swiping left and waiting 3-10 seconds for the next photo to be downloaded would be much of an improvement over hitting back, and tapping the next one.
