Add option to only hide image from general photo stream

[RubenKelevra]

I thought when I hide a picture it gets removed from the General Picture Stream - but would still show up when previously added to an album (or in the automatically created albums.

I like to recommend a change in the UX, if this is really the intended purpose: Implement an archive function which works like the Google Photos one, which lets me remove pictures from the photo stream once sorted. Maybe even automatically remove all "sorted into album" pictures.

In Addition it would be very nice to have the possibility to toggle the visibility of an whole album in the main feed.

So set an album to hidden -> add a photo from main feed -> photo disappears from main feed, but not from album
