Hide hidden (dot) files/folders for private/archived photos

[Gremious]

Pigallery mirrors filesystem directories, so it would be nice if it also hid dotfiles/dotfolders by default, with a button to show them.

They should still be shareable via sharelinks - this should be just a nice simple way to implement private or archived photos, so that they don't clutter, or show up when accessing pi-gallery around people.

Off the top of my head, I'm hoping it's as simple as "if the path to this files contains an item starting with a dot, don't show it unless a setting is flipped".

I had a similar request for unlisted directories in #661
